连续的数中，奇数和偶数数目相差最大为1。注意特判0的情况。

#include <algorithm>#include <iostream>#include <cstring>#include <cstdlib>#include <cstdio>#include <cmath>using namespace std;int main(void){    int n,m;    scanf("%d %d", &n, &m);    if ((abs(n-m)<=1)&&(n!=0||m!=0))        printf("Yes\n");    else        printf("No\n");    return 0;}
