Add Two Integers
Problem Statement
Given two integers num1
and num2
, return the sum of the two integers.
Examples
Example 1:
Input: num1 = 12, num2 = 5
Output: 17
Explination: num1 is 12, num2 is 5, and their sum is 12 + 5 = 17, so 17 is returned.
Example 2:
Input: num1 = -10, num2 = 4
Output: -6
Explination: num1 + num2 = -6, so -6 is returned.
Constraints
-100 <= num1, num2 <= 100
Solution
C++ Implementation
class Solution {
public:
int sum(int num1, int num2) {
return num1 + num2;
}
};
Python Implementation
class Solution:
def sum(self, num1: int, num2: int) -> int:
return num1 + num2
Java Implementation
class Solution {
public int sum(int num1, int num2) {
return num1 + num2;
}
}
JavaScript Implementation
var sum = function(num1, num2) {
return num1 + num2;
};
TypeScript Implementation
function sum(num1: number, num2: number): number {
return num1 + num2;
};
Conclusion
These implementations handle the addition of two integers and return their sum. The examples provided also show how to use each function. The problem is straightforward and has a constant time complexity of 𝑂(1) for each implementation.
