第一个getchar()是用来吸掉cin后第一个'\n'

by ikunTLE @ 2024-08-10 19:46:32

@Shy_Vector 换行符问题，是\r\n，改后：

#include <iostream>
using namespace std;

const int dig[5][10] = {
    {0b111, 0b001, 0b111, 0b111, 0b101, 0b111, 0b111, 0b111, 0b111, 0b111},

    {0b101, 0b001, 0b111, 0b111, 0b111, 0b111, 0b111, 0b001, 0b111, 0b111},

int main() {
    int n, nums[100];
    cin >> n;
    getchar();getchar();
    for (int i = 0; i < n; i++) {

@ikunTLE 十分感谢！我用vscode写的，看来是vscode和洛谷的输入输出有些区别

by ikunTLE @ 2024-08-10 19:51:54

@Shy_Vector 不是，这个数据是在 Windows 环境下造的

by ikunTLE @ 2024-08-10 19:54:08

@Shy_Vector 你的代码是对的，是数据的问题

by Babadi_Baaa @ 2024-08-17 22:13:51

样例错了，你没有发现0和一之间多了一行吗?
