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
    uint16_t val;
    int check = 1;
    int i = 0;
    while(check){
        val = (reg << i) | (reg >> (16-i));
        val &= 0xFFFF;
        if(val == target){
            return 1;
            check = 0;
        }
        else if(i>=16){
            check = 0;
            return 0;
        }
        else{
            i++;
        }
    }
}

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