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
    int n=1;
    uint16_t tmp=0;
    while(n<=16) {
        tmp = ((reg << n) | (reg >> (16-n)));
        // printf("%d\n",tmp);
        if(tmp == target) return 1;
        n++;
    }

    n=1; tmp=0;
    while(n<=16) {
        tmp = ((reg >> n) | (reg << (16-n)));
        if(tmp == target) return 1;
        n++;
    }

    return 0;
}

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