Detect Circular Pattern Match

Code

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    int res=0;
    for( int i=0;i<16;i++)
    {
        reg= (reg>>1) | ((reg<<15));
        if (reg==target)
        {
            res=1;
            break;
        }
    }
    return res;
}

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