log of base 2 means given variable is power of 2. So

void main(){
int x;
if(x&(x-1){
printf("Given Number is not log base 2\n");
}

}

Write out a function that prints out all the permutations of a string. For example, abc would give you abc, acb, bac, bca, cab, cba. You can assume that all the characters will be unique.
