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
    if(reg == target) return 1;
    uint32_t combined = reg << 16 | reg;
    for(uint8_t i = 1; i < 16; i++){
        uint16_t check = (uint16_t)((combined >> i) & 0xFFFF);
        if(check == 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;
}
