Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    int n,k;
    uint16_t result = 0;
    n = 0;
    k = 0;
    do{
        if((val & (1<<n)) != 0) result |=  (1<<k);  
        k+= 2;
        n ++;
            
    }while (n < 8);
    
    return result;
}

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

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