Detect Circular Pattern Match

Code

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    int f=0;
    uint16_t left,right;
    for(int i=0; i<16;i++){
   left=(target<<i)|(target>>(16-i));
   right=(target>>i)|(target<<(16-i));
    if(reg==left | reg==right){ 
        f=1;
    }
   
    }return f;
}

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