Predefined Functions of C++ for the conversion of Binary Number into Decimal Number

Code Implementation using Predefined Functions of C++ for the conversion of Binary Number into Decimal Number

#include <iostream>
using namespace std;

int main()
{
    char binaryNumber[] = "1010";
    
    cout << stoi(binaryNumber, 0, 2);

    return 0;
}

Time Complexity: The time complexity of this implementation of converting binary numbers into decimal numbers is O(N) where N is the length of the string.

Space Complexity: The space complexity of this implementation of converting a binary number into a decimal number is O(1).
