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 newval = 0;
    for(int i=0;i<=7;i++)
    {
        uint16_t bit  = val>>i &0x1;
        newval |= bit << (2*i);
    }
    return newval;
}

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

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