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 out = 0;
    int j = 0;   
    for (int i = 0; i < 16; i += 2) {
        uint8_t bit = (val >> i) & 1;
        out |= (bit << j);
        j++;}
    return out;

}

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

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