Detect Circular Pattern Match

Code

#include <stdio.h>
#include <stdint.h>
uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    int i=0;
    uint16_t r_temp1;
    uint16_t r_temp2;
    while(i<16){
        uint16_t temp1=reg<<1;
        uint16_t temp2=reg>>16-1;
        reg=temp1|temp2;
        if(reg==target){
            return 1;
        }
        else
        i++;
    }
    return 0;
}

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