Detect Circular Pattern Match

Code

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    uint16_t AddRegister = 0;
    for (int i=15 ; i>=0 ; i--)
    {
        AddRegister = (reg << i) | (reg >> (16 - i));
        if(AddRegister == 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;
}
