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
    uint8_t bit=0;
    uint8_t rotco=0;
    for(uint8_t i=0; i<32; i++){
        if(reg==target) return 1;
        bit = reg & 0x01;
        reg>>=1;
        reg |= (bit<<15);
    }
    return 0;

}

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

Just rotate for 0 to 15 and then if one of them is matching target then output is 1
