Detect Circular Pattern Match

Code

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    uint16_t bits1, bits2;
    for (int i = 0; i < 16; i++) {
        bits1 = (reg >> i);
        bits2 = (reg << (16 - i));
        reg = bits1 | bits2;
        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;
}
