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 num=0,j=0;
    for(int i=0;i<16;i++)
    {
        if(i%2==0)
        {
            if(val>>i&1)
            {
                num|=1<<j;
            }
            j++;
        }

    }
    return num;
}

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

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