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 resul = 0 ;
    uint8_t arr[8];
    uint8_t i = 0;
    uint8_t du = 0;
    while(val / 2 != 0)
    {
        du = val % 2 ;
        val = val / 2;
        arr[i] = du ;
        i++;
    }
    arr[i++] = 1;
    for(uint8_t j = 0 ; j < 8 ; j++)
    {
        resul = resul | (arr[j]) << (j*2);
    }
    return resul;
}

int main() {
    uint8_t val;
    scanf("%hhu", &val);
    uint16_t result = spread_bits(val);
    printf("%u", result);
    return 0;
}
