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 new_val = 0;

    for(int i=15;i>=0;i--){
        if((i%2)==0){
            new_val = new_val << 1;
            new_val = new_val | (val >> i)&1;
        }
    }
    return new_val;
}

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

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