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 ans=0;
    for(int i=0;i<16;i++){
        if(i%2==0){
        uint8_t bits=(val>>i)&1;
        ans|=(bits<<(i/2));
        }
        }
    
    return ans;
}

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

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