Brute Force

A brute force algorithm is a straightforward approach to solving a problem that relies on systematically checking all possible solutions.

While it's often not the most efficient method, it can be useful for solving smaller scale problems or as a starting point for more optimized algorithms.

pseudocode:

BruteForceAlgorithm(input):
    // Initialize any necessary variables
    result = None

    // Iterate through all possible combinations or options
    for each option in allOptions:
        // Check if the current option satisfies the condition
        if condition(option, input):
            // Update the result if necessary
            result = updateResult(result, option)

    return result

function factorial(n) {
  if (n === 0 || n === 1) {
    return 1;
  } else {
    let result = 1;
    for (let i = 2; i <= n; i++) {
      result *= i;
    }
    return result;
  }
}

console.log(factorial(5)); // Output: 120 (5! = 5 * 4 * 3 * 2 * 1 = 120)

In this example, the factorial function calculates the factorial of a given number n using a brute force approach.

It iteratively multiplies the numbers from 1 to n to calculate the factorial.

Brute force algorithms can be inefficient for large-scale problems because they often involve checking every possible solution, which can lead to high time complexity.

However, they are simple to implement and can be a good starting point for solving problems before optimizing further.
