Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    int8_t count = 7;
    uint16_t result = 0;
    while(count >= 0)
    {
        result <<= 2;
        result |= ((val & (0x1 << count)) >> count);
        count--;
    }
    return result;
}

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

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