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 = 1;
    uint16_t val = 0;


    for(uint8_t i=0; i<16; ++i)
    {
        val = (reg >> 15) & mask;
        reg <<= 1;
        reg |= val;

        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;
}
