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 result =0;
    int bit_position =0;
    for (int i=0; i<16; i+=2){ // skip every other
        if(val & (1 << i)){
            result |= (1 << bit_position);
        }
        bit_position++;
    }
    return result;
}

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

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