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 mask =0;
    if(reg == target)
    return 1;
    for(int i =0; i<16; i++)
    {
        mask = reg&1;
        reg >>=1;
        reg|= mask<<15;
        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;
}
