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 n = 0;
    uint8_t mask = 1;

    for(uint8_t i = 0; i<16; i+=2)
    {
        uint8_t temp = (val & mask);

        if(temp)
        {
            n |= (1<<i);
        }
        mask <<= 1;

    }

    return n;
}

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

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