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 cnt = 0;
    uint8_t reg_8 = 0 ;
    uint8_t bit_mask = 0;
    for(uint8_t i = 0 ; i < 16 ; i++)
    {
        if ( i % 2 == 0)
        {
            bit_mask = (val>>i) & 0x01;
            reg_8 |= (bit_mask << cnt);
            cnt++;
        }
    }
    return reg_8;
}

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

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