西工大–人工智能程序设计noj–前60道

前言
截止到2022.12.10,本课程的noj61——90道,由于需要用到numpy、pandas、scipy等库,系统暂时没有这些库,无法评判,所以暂且分享一下前60道。前60道都已经AC(AC的截图我放在最后了)。有些题我小题大做了,程序写的很复杂,比如前10道;另外有些题的代码写的不太好,最近考试要紧,以后有时间再优化吧。如果有问题或者需要改进的地方,欢迎大家提供意见批评指正。
此文章仅供学习交流参考。本人也是初学python不久。

ps:前几道题没有截图,后面的都有。and图片有点大emm

1.Hello World

print("Hello World")

2.整数运算

a = int(input())
b = int(input())
c = input()
if (c == '+'):
    print("%d+%d=%d" % (a, b, a+b))
elif (c == '-'):
    # print("{}{}{}={}".format(a, c, b, a-b))
    print("%d-%d=%d" % (a, b, a-b))
elif (c == '*'):
    # print("{}{}{}={}".format(a, c, b, a*b))
    print("%d*%d=%d" % (a, b, a*b))
elif (c == '/'):
    if (b == 0):
        print("ERROR")
    else:
        # print("{}{}{}={}".format(a, c, b, a/b))
        print("%d/%d=%f" % (a, b, a/b))
elif (c == '//'):
    if (b == 0):
        print("ERROR")
    else:
        # print("{}{}{}={}".format(a, c, b, a//b))
        print("%d//%d=%d" % (a, b, a//b))
elif (c == '%'):
    if b == 0:
        print("ERROR")
    # print("{}{}{}={}".format(a, c, b, a % b))
    else:
        print("%d%%%d=%d" % (a, b, a % b))
elif (c == '**'):
    if a==0 and b == 0:
        print("ERROR")
    else:
    # print("{}{}{}={}".format(a, c, b, a**b))
        print("%d**%d=%d" % (a, b, a**b))
else:
    print("ERROR")

3.动态宽度

a = int(input())
b = int(input())
m = ''
while a > 0:
    m += str(a % 2)
    a = a//2
if len(m) > b:
    print(m[len(m)-b-1:-1])
else:
    for i in range(b-len(m)):
        print("0", end="")
    print(m[::-1])

4.二进制,八进制和十六进制

b = input()
d = input()
o = input()
h = input()
hhh = {'0': 0, '1': 1, '2': 2, '3': 3, '4': 4, '5': 5, '6': 6, '7': 7, '8': 8,
       '9': 9, 'a': 10, 'b': 11, 'c': 12, 'd': 13, 'e': 14, 'f': 15}
h_list = ['0', '1', '2', '3', '4', '5', '6',
          '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f']
bb = 0
dd = 0
oo = 0
hh = 0
for i in range(len(b)):
    bb += int(b[i]) * 2 ** (len(b)-i-1)
for i in range(len(d)):
    dd += int(d[i]) * 8 ** (len(d)-i-1)
oo = int(o)
for i in range(len(h)):
    hh += hhh[h[i]] * 16 ** (len(h)-i-1)
# print(bb,dd,oo,hh)
max_number = max(bb, dd, oo, hh)
# print(max_number)
a = max_number
m = ''
while a > 0:
    m += str(a % 2)
    a = a//2
print("0b"+m[::-1], end=",")
a = max_number
m = ''
while a > 0:
    m += str(a % 8)
    a = a//8
print("0o"+m[::-1], end=",")
print(max_number, end=",")
a = max_number
m = ''
while a > 0:
    m += h_list[a % 16]
    a = a//16
print("0x"+m[::-1])

5.回文数

这题我之前在别的地方写过,不过要求更多,这里就直接拿过来用了

def dp(sstr):
    lenth = len(sstr)
    l, r = 0, 0
    dp = [[False] * lenth for i in range(lenth)]
    for i in range(lenth - 1, -1, -1):
        for j in range(i, lenth):
            if sstr[i] == sstr[j]:
                if j - i <= 1:
                    dp[i][j] = True
                elif dp[i+1][j-1]:
                    dp[i][j] = True
            if dp[i][j] and j - i > r - l:
                l, r = i, j
    return sstr[l:r+1]


if __name__ == '__main__':
    num=int(input())
    str1=[]
    for i in range(num):
        str=input()
        str1.append(str)
    if num != 0:
        for i in range(num-1):
            if len(str1[i]) == len(dp(str1[i])):
                print("True",end=",")
            else: print("False",end=",")
        if len(str1[-1]) == len(dp(str1[-1])):
            print("True")
        else: print("False")

6.加密

a = int(input())
b = int(input())
c = int(input())
a = (a+b) % c
a = str(a)
if len(a) >= 4:
    for i in range(4):
        print(a[-i-1],end="")
else:
    print(a[::-1],end="")
    for i in range(4-len(a)):
        print("0",end="")

7.字符串处理

import sys

n = int(input())
slist = []
min_length = 10000
same_length = 0
for i in range(n):
    strlist = input()
    if (len(strlist) < min_length):
        min_length = len(strlist)
    slist.append(strlist)
if n != 0 and n!=1:
    for i in range(min_length):
        s = slist[0][i]
        same_length = i+1
        for j in range(n):
            if (slist[j][i] == s):
                continue
            else:
                same_length = i
                if same_length == 0:
                    print("None")
                    sys.exit()
                else:
                    for i in range(same_length):
                        print(slist[0][i], end="")
                    sys.exit()
    for i in range(same_length):
        print(slist[0][i], end="")
elif n == 1:
    print(slist[0])
else:
    print("None")

8.复数的和差积商

c1=complex(input())
c2=complex(input())
print(c1+c2,end=",")
print(c1-c2,end=",")
print(c1*c2,end=",")
print(c1/c2,end=",")
print(c1.conjugate(),end=",")
print(abs(c1))

复盘:

这题我考虑复杂了,没想到python提供了复数类型complex,在知道提供了complex类型后,我还想要自己实现共轭和模,本来是想找到实部和虚部,然后输出self.x2+self.y2,然后再用cmath.sqrt()方法取根号,结果取完根号它输出的并不是一个数(形式),而是复数的形式,比如3+4j的模是5,这样输出的结果并不是5而是5+0j,这样一种复数形式。查找资料后找到原因:

在网上找到了complex的源码:

#  用类实现复数的运算
 
class Complex:  # 定义Complex类
    def __init__(self, x, y):
        self.x = x
        self.y = y
 
    # 定义方法 加 ,可用魔法方法__add__()
    def __add__(self, other):
        return Complex(self.x + other.x, self.y + other.y)  # 返回两个值的相加结果
 
    # 定义方法 减 ,可用魔法方法__sub__()
    def __sub__(self, other):
        return Complex(self.x - other.x, self.y - other.y)  # 返回两个值的相减结果
 
    # 定义方法 乘 ,可用魔法方法__mul__()
    def __mul__(self, other):
        return Complex(self.x * other.x - self.y * other.y, other.x * self.y + self.x * other.y)  # 返回两个值的复数相乘结果
 
    # 定义方法 除 ,可用魔法方法__truediv__()
    def __truediv__(self, other):
        return Complex((self.x * other.x + self.y * other.y) / (other.x * other.x + other.y * other.y),
                       (other.x * self.y - self.x * other.y) / (other.x * other.x + other.y * other.y))  # 返回两个值的复数相除结果
 
    def __str__(self):
        return "%d + %di" % (self.x, self.y)
 
 
c1 = Complex(2, 4)  # 2 + 4i,传入实部2,虚部4
c2 = Complex(3, 1)  # 3 + i,传入实部3,虚部1
c3 = c1 + c2  # 将相加结果赋值给c3 ,这里由于加号,自动触动上面的魔法方法add,下同
c4 = c1 - c2  # 将相减结果赋值给c4
c5 = c1 * c2  # 将相乘结果赋值给c5
c6 = c1 / c2  # 将相除结果赋值给c6
print(c3)
print(c4)
print(c5)
print(c6)

重点在于25行的

​ def str(self):

​ return “%d + %di” % (self.x, self.y)

魔术方法,意思是所有类输出的结果的形式都要类似于这样"%d + %di"。

9.all-any

西工大noj,python,开发语言,人工智能

num=int(input())
a=[]
flag=0
for i in range(num):
    if flag==0:
        flag+=1
    else:
        print(",",end="")
    a=bin(int(input()))
    b=list(a[2:])
    for i in range(len(b)):
        b[i]=int(b[i])
    print(all(b),end="")

10.罗马数字

num=int(input())
flag=0
dist = {'M':1000,'D':500,'C':100,'L':50,'X':10,'V':5,'I':1}

for i in range(num):
    if flag==0:
        flag+=1
    else:
        print(",",end="")
    st=input()
    result=0
    for j in range(len(st)):
        if j>0 and dist[st[j-1]] < dist[st[j]]:
                result=result+dist[st[j]]-2*dist[st[j-1]]
        else:
            result+=dist[st[j]]
    print(result,end="")

这题啥波一了,最后每次输出多了一个换行,忘记end=""了。。。。写了一个多小时。

11.搜索插入位置

num_list=input().split(",")
look_for=input()
if look_for in num_list:
    print(num_list.index(look_for))
else:
    for i in range(len(num_list)):
        if look_for > num_list[i]:
            continue
        else:
            print(i)
            break

12.重复数字

test_list=input().split(",")
for i in range(len(test_list)):
    test_list[i]=int(test_list[i])
data_dict={}
for i in test_list:
    if i not in data_dict.keys():
        data_dict[i]=1
    else:
        data_dict[i]+=1
# print(dict(sorted(data_dict.items(),key=lambda x: -x[1])))
print(dict(sorted(data_dict.items())))

这题学到的东西还是比较多的。

注释的那一行是按照values降序排序

参考一个很好的博客:http://t.csdn.cn/btqpV

13.百分制成绩转换五分制

score=int(input())
if score>100:
    print("data error!")
elif score>=90:
    print("A")
elif score>=80:

elif score>=70:
    print("C")
elif score>=60:

elif score>=0:
    print("E")
else:
    print("data error!")

            if not i.isdigit():
                return False
        return True

def str2float(str):
    s=str.split(".")
    return int(s[0])+int(s[1])/(10**len(s[1]))

num=0
num_str_list=input().split()
for i in range(len(num_str_list)):
    if num_str_list[i].isdigit():
        num_str_list[i]=int(num_str_list[i])
        num+=num_str_list[i]
    elif isfloat(num_str_list[i]):
        num_str_list[i]=str2float(num_str_list[i])
        num+=num_str_list[i]
print(num_str_list)
print(num)

16.反转元组
