Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) {
    
    uint8_t ans = 0x0;

    uint8_t bits_counter = 0x0;

    for(uint8_t i=0;i<16; i+=2)
    {
        if((val>>i)&0x1)
        {
            ans |= (1<<bits_counter);
        }

        bits_counter++;
    }

    return ans;
}

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

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