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 i =0 ;
    while(i<16){
        if ((((reg << 1)|(reg >> 15))&0xFFFF) == target){
            return 1;
        }
        reg = (((reg << 1)|(reg >> 15))&0xFFFF);
        i++;
    }
    
    return 0;
}

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