Write a function called centeredAverage that takes two parameters: an array of integers and the number of elements in the array and returns the "centered" average of the array.

Define the "centered",average to mean the floating point average of the values, except ignoring a single occurrence of the largest and'smallest values in the array. If there are multiple copies of the smallest value, ignore just one copy, and likewise for the largest value. You may assume that the array is of length $3$ or more.

centeredAverage $(\{1,100,3,4,2\},5)$ returns $3\mathrm{.}0(ignore1$ and $100)$

centeredAverage $(\{1,1,5,5,10,8,7\},7)$ returns $5\mathrm{.}2(ignore1$ and $10)$

centeredAverage $(\{-10,-4,-2,-4,-2,0\},6)$ returns $-3\mathrm{.}0(ignore0$ and $-10)$

Write the entire function below, including the function header.

Note : In the examples above of calling the function, the values within curly brackets $\{\}$ indicate an input array parameter.
