C :

#include<stdio.h>
 
 
int main() {
    int n, men, women, children;
    scanf("%d", &n);
    // 小孩制定是2的倍数个人，所以每次+2
    for (children = 0; children < 39; children+=2) {
        for (men = 0; men <= 20; men++) {
            women = 36 - children - men;
            if(women >=0 && (children/2 + men*4 + women*3) == n){
                printf("men=%d,women=%d,children=%d\n", men, women, children);
            }
        }
    }
}
