C :

#include <stdio.h>
int main(){
	int n;
	unsigned int a;
//	freopen("1.txt","r",stdin);
	while(scanf("%u %d",&a,&n)==2){
		printf("%u\n",(a>>n|a<<(32-n)));
	}
//	fclose(stdin);
	return 0;
}

C++ :

#include <stdio.h>
int main() {
	unsigned int a, temp;
	int n;
	scanf("%u %d", &a, &n);
	temp = a & ((1 << n) - 1);
	printf("%u\n", (a >> n) | (temp << (32 - n)));
	return 0;
}
