Bit Spreading Interleave Bits with Zeros

Code

#include <stdio.h>
#include <stdint.h>

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    uint16_t res = 0; 
    int count = 0; 
    for ( int i=0 ; i < 8 ; i ++)
    {
        if ( val & (1 << i) )
        {
            res |= ( 1 << count);
        }
        else 
        {
            res &= ~( 1 << count);
        }
        
        // printf("%d %d \n", res,count);
        count += 2;
    }
    return res;
}

int main() {
    uint8_t val;
    scanf("%hhu", &val);

    uint16_t result = spread_bits(val);
    printf("%u", result);
    return 0;
}
