#include <stdio.h>#include <string.h>int main(){char wanted[1001], shop[1001];int need[62],i,flag=0;scanf("%s %s", shop, wanted);for (i = 0; i < 62; i++)need[i] = 0;for (i = 0; wanted[i] != '\0'; i++) {if (wanted[i] >= '0' && wanted[i] <= '9')need[wanted[i] - '0']++;else if (wanted[i] >= 'A'&&wanted[i] <= 'Z')need[wanted[i] - 'A' + 10]++;else need[wanted[i] - 'a' + 36]++;}for (i = 0; shop[i] != '\0'; i++) {if (shop[i] >= '0' && shop[i] <= '9')need[shop[i] - '0']--;else if (shop[i] >= 'A'&&shop[i] <= 'Z')need[shop[i] - 'A' + 10]--;else need[shop[i] - 'a' + 36]--;}for (i = 0; i < 62; i++)if (need[i]>0) {flag = 1;break;}if (!flag)printf("Yes %d",strlen(shop)-strlen(wanted));else {int missing=0;while(i<62){if (need[i]>0)missing += need[i];i++;}printf("No %d",missing);}return 0;}
