【LetMeFly】2235.两整数相加:19种语言解法(力扣全解法)
力扣题目链接:https://leetcode.cn/problems/add-two-integers/
给你两个整数 num1
和 num2
,返回这两个整数的和。
示例 1:
输入:num1 = 12, num2 = 5 输出:17 解释:num1 是 12,num2 是 5 ,它们的和是 12 + 5 = 17 ,因此返回 17 。
示例 2:
输入:num1 = -10, num2 = 4 输出:-6 解释:num1 + num2 = -6 ,因此返回 -6 。
提示:
-100 <= num1, num2 <= 100
方法一:返回num1 + num2
- 时间复杂度 O ( 1 ) O(1) O(1)
- 空间复杂度 O ( 1 ) O(1) O(1)

public:
int sum(int num1, int num2) {
return num1 + num2;
}
};

(-> exact-integer? exact-integer? exact-integer?)
(+ num1 num2)
)
