Create a function called `findExpression` that takes a number as parameter and returns a string
Create a function named `findExpression` that takes a `number` as parameter and returns a `string`.
- It will be given two constant variable `add4` and `mul2`
- Your goal is to try to find a sequence, starting from the number 1, and repeatedly either adding 4 or multiplying 2
that produces the number given has parameter.
For example, the number 8 you must first multiplying by 2 twice and then add 4.
It will look something like this `1 *2 *2 +4`
- 2 constant variables will be made available to your function: `add4` and `mul2`.
- Your goal is to try to find a sequence, starting from the number 1, and repeatedly either adding 4 or multiplying by 2, to produce the number given as a parameter.
- If the number can not be reached you should return `undefined`
- If the number can not be reached you should return `undefined`
For example, for the number `8`, you must first multiply by 2 twice, and then add 4. Your function should return something like: `1 *2 *2 +4`.
