#include<stdio.h>
int main()
{int l,m,a[10001],i,s[101],j[101],c,b;
scanf("%d%d",&l,&m);
for(i=0;i<m;i++)

@hyc12528 好的好的，老师都不教代码，让我们自己写的，好多人说我代码格式有点不好，请问我咋改进呢

@lww0903 我发个参考(修改了)，还有问题都说了

#include <stdio.h>
int main() {
    int l, m, a[10001], i, s[101], j[101], c, b = 0;
    scanf("%d%d", &l, &m);
    for (i = 0; i < m; i++)
        scanf("%d%d", &s[i], &j[i]);
    for (i = 0; i < l + 1; i++)
        a[i] = 500;
    for (i = 0; i < m; i++) {
        for (c = s[i]; c <= j[i]; c++)
            a[c] = 1;
    }
    for (i = 0; i < l + 1; i++)
        if (a[i] == 1)
            b++;
    printf("%d", l + 1 - b);
    return 0;
}
