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 result = 0;

    for(int i = 0; i < 8; i++) {
        uint8_t x = (val >> i) & 1; // This moves the value at the i-th bit of val to bit 0 of x
        result |= (x << (2 * i));
    }
    return result;
}

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

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