1. Create an algorithm that runs through a one-dimensional array containing letters and numbers: [ “a”, 10, “b”, “hola”, 122, 15]

• a. Get an array containing just the letters
• b. Get an array containing just the numbers
• c. Get the highest number from the array above

2. Create a hashmap (or a simple object in PHP) that contains the elementary functions of addition, subtraction, multiplication, and division

• a. Take into account that the division must not allow 0 dividend
• b. The sum function allows an array as an input parameter and adds all its elements.
• c. The subtraction function allows an array as an input parameter and subtracts all its elements.
• d. Multiplication Function - Ditto
• e. The division function accepts two parameters: a and b.

3. Create an algorithm that generates the following random ID pattern: XXXX-AAAA-BBBB-CCCC

• a. Where XXXX, AAAA, BBBB and CCCC patterns are random alphanumeric

• b. The default is a string: "XXXX-AAAA-BBBB-CCCC"

• c. The result must be stored in a variable. For example:

  • i. $id = generarId()
  • ii. id is ~ abc1-bb12-234a-bcc2
