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 new_val = 0;
    for (uint8_t i = 0; i < 8; i++) {
        if (val & (1 << i)) {
            new_val += (1 << (i * 2));
        }
    }
    return new_val;
}

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

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