#include<stdio.h>
int main()
{
	int a=0, b=0, c=0, i;
    char s[3];
	scanf("%s", s);
	
	for(i=0;i<3;i++){
    if(s[i]=='a') a++;
      else if(s[i]=='b') b++;
      else if(s[i]=='c') c++;
      else printf("error\n");
    }
  
  if(a == 1 && b == 1 && c == 1 )
    printf("Yes\n");
  else
    printf("No\n");
 
	return 0;
