Quantifiers

Instructions

Create three functions that receive an array and a function each:

• every that returns true if every element of the array respects the condition of the received function and false otherwise.
• some that returns true if at least one element of the array respects the condition of the received function and false otherwise.
• none that returns true if none of the elements of the array respects the condition of the received function and false otherwise.

The use of [].every and [].some is forbidden for this exercise.
