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
    uint16_t newreg;
    for (int i = 0; i<=15; i++){
        newreg = ((reg>>i) | (reg<<(16-i)));
        if(newreg == 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;
}

Solving Approach

Just rotate for 0 to 15 and then if one of them is matching target then output is 1
