题目描述:

知识点:数据越界

思路:用long型变量保存输入值,以防越界

时间复杂度是O(n),其中n为输入的数据对数。空间复杂度是O(1)。

C++代码:

#include<iostream>

using namespace std;

int main() {
	int count;
	cin >> count;
	long num1 = 0;
	long num2 = 0;
	long num3 = 0;

	for (int i = 1; i <= count; i++) {
		cin >> num1 >> num2 >> num3;
		if (num1 + num2 > num3) {
			cout << "Case #" << i << ": " << "true" << endl;
		} else {
			cout << "Case #" << i << ": " << "false" << endl;
		}
	}
}

JAVA代码:

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int count = Integer.parseInt(scanner.nextLine());
        for (int i = 1; i <= count; i++) {
            String[] strings = scanner.nextLine().split("\\s+");
            Long[] nums = new Long[3];
            for(int j = 0; j < 3; j++){
                nums[j] = Long.parseLong(strings[j]);
            }
            if(nums[0] + nums[1] > nums[2]){
                System.out.print("Case #" + i + ": " + true);
            }else{
                System.out.print("Case #" + i + ": " + false);
            }
            if(i != count){
                System.out.println();
            }
        }
    }
}
