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;
    int pos = 0;
    for(int i=0; i<16; i=i+2)
    {
        int bit = (val>>i) & 1;   
        num |= bit << pos++;   

    }
    return num;
}

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

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