33. Detect Circular Pattern Match

#include <stdio.h>
#include <stdint.h>

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
   for(int i=0; i<16; i++) {
    uint16_t rotate = ((reg << i) |(reg >>( 16 - i)));
    if(rotate == target) return 1;
   }
    return 0;
}

int main() {
    uint16_t reg, target;
    scanf("%hu %hu", &reg, &target);
    printf("%hhu", is_circular_match(reg, target));
    return 0;
}
