33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    uint16_t bit,res=reg,news;
    int i,pos;
    for(i=1;i<=15;i++){
        res=(res<<1);
        bit=reg>>(16-i)&1;
        res|=bit<<0;
        news=res&0xFFFF;
        if(news==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;
}
