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 ret = 0;
    for (uint8_t i = 0; i < 16; i += 2) {
        ret |= (((val >> i) & 0x1) << (i / 2));
    }

    return ret;
}

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

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

Solving Approach

My logic is same to the solution
