least significant bit is 0 or 1

The program must accept an integer N as the input. The program must print YES if the least significant bit of N is set as 1. Else the program must print NO as the output.

Example Input/Output 1:
Input:

Output:
YES

solution:

int main()

{

int a;

scanf("%d",&a);

if(a&1==1){

    printf("Yes");}

else{

    printf("no");

}

}
