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

$1.$ Prints "Good" if there is an element in the array, called "BigNumber," whose value equals the sum of all even elements $($excluding itself$).$

$2.$ 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$).$

$3.$ Otherwise, prints $"$NO$"$

For example:

$1.$ For the array arr $=[1,2,4,2],$ the output is "Good" because an$[2]=4$ is equal to

the sum of all even elements $($ar$[2]-$ an $[1]+$ arr$[31).$

$2.$ For the array ar $=[2,3,2,3,41,$ the output is "VeryGood" because an$[4]=4$ is

equal to the sum of all even elements. Additionally, swapping it with an$(2]$ makes the array a palindrome.

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

BigNumber.
