Implement a function makeCounter that accepts an optional integer value and returns a function. When the returned function is called for the first time, it returns the initial value if provided; otherwise, it returns 0. Each subsequent call to the returned function returns a value that is 1 greater than the value returned in the previous invocation.

You are given an array 'ARR' of 'N' integers and you have to calculate 3 things for the given array:-

1. Mean - function mean(): This function should calculate the mean of the array.

2. Median - function median(): This function should calculate the median of the array.

3. Mode - function mode(): This function should calculate the mode of the array.

Note :

It can be shown that Mean and Median is in the form of P/Q, where P and Q are coprime integers and Q != 0. You need to return P and Q.

For Mode, if the highest frequency of more than one element is the same, return the smallest element.

For Example, for the given array {1, 1, 2, 2, 3, 3, 4}, the mode will be 1 as it is the smallest of all the possible modes i.e 1, 2 and 3.
