Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) {
    // Your logic here
    
    uint8_t rev =0x0;
    uint8_t temp;
    int j=0;

    for(int i=0; i<16; i++)
    {
        temp = (val>>i) & 1;
        rev |= (temp << j);
        j++;
        i++;
    }

   //val &= 0x5555;
    //val = (val | val<<2) & 0x3333;
    //val = (val | val<<4) & 0X00FF;

   return rev;
}

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

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