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 n=0,j=0,pos;
    for(pos=0;pos<=15;pos+=2)
    {
        if(val&(1<<pos))
        n|=(1<<j);
        j++;
    }

    return n;
}

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

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