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

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