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
    // O(n) - Solution
    uint16_t temp = reg;

    for(int i = 0; i < 16; i++) {

        // Circular right shift
        temp = (reg >> i) | (reg << (16-i));

        if(temp == 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;
}
