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 new_reg=0;
  for(int i=0;i<16;i++){
  int bit=(reg>>(i*2))& 1;
   new_reg|=bit<<i;

  }  
  return new_reg;
}

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