33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    
    uint16_t val = reg;
    int matchCount = 0;

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

        if(val==target) return 1;
        val = (val<<1) | (val>>15);

    }

    return 0;
}

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