22. Extract Even Bits Only from 32-bit Register

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

uint32_t extract_even_bits(uint32_t reg) {
    // Your code here
    uint32_t reg1 = 0;
    for(int i =0 ;i<32 ;i+=2){
       
       if(reg & (1<<i)){
       
       reg1|=(1<<(i/2));
       }
    }
    return reg1;

int main() {
    uint32_t reg;
    scanf("%u", &reg);
    printf("%u", extract_even_bits(reg));
    return 0;
