Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) {
    // Your logic here

uint16_t temp = 0;
uint8_t reg =0;

for(int i=0; i<=15; i+=2)
{
   temp = val&1;

   reg |=temp<<i/2;

   val>>=2;
 
   
}

    return reg;
}

int main() {
    uint16_t val;
    scanf("%hu", &val);

    uint8_t result = compress_bits(val);
    printf("%u", result);
    return 0;
}
