// Write a function called generatePassword that takes three parameters: length, includeNumbers,
// and includeSpecialChars. The function should generate a random password of the given length.
// If the user doesn't specify whether to include numbers or special characters, the function should default to including them.

// includeNumbers is a boolean that indicates whether to include numbers in the password. Default to true.
// includeSpecialChars is a boolean that indicates whether to include special characters. Default to false.

// The function should ensure that the generated password meets the following conditions:

// Contains at least one uppercase letter.
// If includeNumbers is true, includes at least one number.
// If includeSpecialChars is true, includes at least one special character (like @, #, !).

// If generatePassword(10, true, true) is called, it might return a password like "Ab1@deF2Gh".

// function generatePassword(
//   len,
//   includeNumbers = "true",
//   includeSpecialChars = "false"
