33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    for(int i =16;i>=0;i--)  {
        reg = (uint16_t)reg<<i | (uint16_t)reg>>(16-i);
        if (reg == 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;
}
