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 (uint8_t i=0;i<16;i++){
    uint32_t first = (reg&0x1)<<15;
    reg >>= 1;
    reg|=first;
    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;
}
