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
    if (reg==target) return 1;
    uint16_t tem = reg;
    for (int i = 0; i<16; i++){
        tem = (tem<<1)|(tem>>(15));
        if (tem==target) return 1;
    }
    tem = reg;
    for (int i = 0; i<16; i++){
        tem = (tem>>1)|(tem<<(15));
        if (tem==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;
}
