// Binary to Decimal using pow()
#include <iostream>

int main() {
    long long binaryNumber;
    std::cout << "Enter a binary number: ";
    std::cin >> binaryNumber;

    long long decimalNumber = 0;

    int remainder;

    // Step 1: Loop while the binary number is not zero
    while (binaryNumber != 0) {
        // Step 2: Get the last digit (remainder)

        // Step 3: Remove the last digit from the binary number
        binaryNumber /= 10;
        // Step 4: Add (remainder * 2^i) to decimalNumber
        decimalNumber += remainder * std::pow(2, i);
