Detect Circular Pattern Match

Code

#include <stdio.h>
#include <stdint.h>

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    uint16_t i = 0;
    uint16_t num;
    
    while(i < 16)
    {
        num = ((reg<<i) | (reg>>(16 - i)));
        if(num == target)
            return 1;
        i++;
    }

    return 0;
}

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