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
    
    for(uint8_t i=0;  i<16; i++){
        if(reg==target){
            return 1;
        }
        
        if(reg & 0x8000){
            reg = (reg<<1) | 0b01;
        }else{
            reg = reg<<1;
        }
        //printf("Reg: %b\n", reg);
    }
    return 0;
}

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