33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    uint8_t check = 0;
    if ( reg == target) return 1;
    else{
        for(int i  = 1; i < 16; i++){
            reg = (reg << i) | (reg >> (16 - i));
            if( reg == 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;
}
