Bit Spreading Interleave Bits with Zeros

Code

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

typedef uint16_t u16;
typedef uint8_t u8;

u16 spread_bits(uint8_t val) {
    // Your logic here
    u16 data;
    for(int i = 0; i < 8; i++) {
        u8 currentVal = (val >> i) & 1;
        if(currentVal) {
            data |= (1 << (i * 2));
        } else {
            data &= ~(1 << (i * 2));
        }
    }
    
    return data;
}

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

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