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

    for (int i=0; i<16; i++) {
        if ((reg & 0xFFFF) == target) {
            return 1;
        }
        reg = (reg >> 1) | (reg << 16-1);
        reg &= 0xFFFF;
    }

    return 0;
}

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