Summary

The problem is about implementing logical operators in programming. The main task is to write a function that takes multiple boolean values as input and returns the result of applying a given logical operator (AND, OR, XOR) to these values.

Detailed Explanation

The approach to solve this problem involves writing a simple function that applies the given logical operator to the input boolean values. We will provide examples for AND, OR, and XOR operators.

For example, if we want to implement an AND operator, our function would return True only when all inputs are True. If any of the inputs is False, the function would return False.

Here's a step-by-step breakdown of the solution:

  1. Define a function that takes multiple boolean values as input.
  2. Initialize a variable to store the result of the logical operation.
  3. Iterate over each input value:
    • For AND operator, update the result variable to True only when all inputs are True.
    • For OR operator, update the result variable to True if any input is True.
    • For XOR operator, update the result variable based on the XOR operation of each input.
  4. Return the result of the logical operation.

Here's an example ASCII art diagram for illustrating the AND operation:

Input 1: True
Input 2: True
Input 3: True
Result: True

Input 1: True
Input 2: False
Input 3: True
Result: False

Input 1: False
Input 2: True
Input 3: True
Result: False

Time complexity for this problem is O(n), where n is the number of input values. Space complexity is O(1) as we only use a constant amount of space to store the result.

    for (boolean input : inputs) {
        if (operator == 'A') { // AND
            result &= input;
        } else if (operator == 'O') { // OR
            result |= input;
        } else if (operator == '^') { // XOR
            result ^= input;
        }
    }
    return result != 0;
