Detect Circular Pattern Match

Code

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

uint8_t set_bits(uint16_t reg){
    int count = 0;
    int i = 31;
    while(i >= 0){
        uint8_t temp = ((reg >> i) & 1);
        if(temp ==  1){
            count++;
            
        }
        i--;
    }

    return count;
}

uint8_t is_circular_match(uint16_t reg, uint16_t target) {

    // wrong solution
    if(set_bits(reg) == set_bits(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;
}
