Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) {
     uint16_t result = 0;

    for (int i = 0; i < 16; i++)
    {
        if (val & (1 << (2 * i)))
        {
            result |= (1 << i);
        }
    }
    return result;
    }

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

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