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;
    ans |= (val&1);
    ans |= (((val >> 2)&1) << 1) ;
    ans |= (((val >> 4)&1) << 2);
    ans |= (((val >> 6)&1) << 3);
    ans |= (((val >> 8)&1) << 4);
    ans |= (((val >> 10)&1) << 5);
    ans |= (((val >> 12)&1) << 6);
    ans |= (((val >> 14)&1) << 7);
    // uint8_t rev = 0;
    // for(int i = 0; i<8; i++){
    //     rev |= ((ans&1)<<(7-i));
    //     ans >>= 1;
    // }

    return ans;
}

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

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