##### ? Challenge 1 *(Easy)*

Write a function to check whether a given string is palindrome.

###### Example

- For
`inputString = "aabaa"`

, the output should be`solution(inputString) = true`

; - For
`inputString = "abac"`

, the output should be`solution(inputString) = false`

; - For
`inputString = "a"`

, the output should be`solution(inputString) = true`

.

##### ? Challenge 2 *(Mid-Easy)*

Write a function to find the pair of adjacent elements that has the largest product from an array of integers and return that product.

###### Example

- For
`inputArray = [3, 6, -2, -5, 7, 3]`

, the output should be`solution(inputArray) = 21`

.

`7`

and `3`

produce the largest product.

##### ? Challenge 3 *(Moderate)*

Below we will define an `n`

-interesting polygon. Write a function to find the area of a polygon for a given `n`

.

A `1`

-interesting polygon is just a square with a side of length `1`

. An `n`

-interesting polygon is obtained by taking the `n - 1`

-interesting polygon and appending `1`

-interesting polygons to its rim, side by side. You can see the `1-, 2-, 3- and 4`

-interesting polygons in the picture below.

###### Example

- For
`n = 2`

, the output should be`solution(n) = 5`

; - For
`n = 3`

, the output should be`solution(n) = 13`

.
