Write a $C++$ function called goodArray that takes a reference to an integer array called arr and does the following:

Prints "Good" if there is an element in the array, called "BigNumber," whose value equals the sum of all even elements $($excluding itself$).$

Prints "VeryGood" if you can swap the "BigNumber" with any other element to make the array a palindrome $($if the array is printed from left to right or printed from right to left the result is the same$).$

Otherwise, prints $"$NO$".$

For example:

For the array arr $=[1,2,4,2],$ the output is "Good" because arr$[2]=4$ is equal to the sum of all even elements $($arr$[2]=$arr$[1]+$arr$[3]).$

For the array arr$=[2,3,2,3,4],$ the output is "VeryGood" because arr$[4]=4$ is equal to the sum of all even elements. Additionally, swapping it with arr$[2]$ makes the array a palindrome.

For the array arr $=[1,2,3,4,5],$ the output is $"NO".$ because there is no BigNumber.

$1=$

$2=$
