. A Nice array is defined to be an array where for every value n in the array, there is also an element n-1 or n+1 in the array.
For example, {2, 10, 9, 3} is a Nice array because
2 = 3-1
10 = 9+1
3 = 2 + 1
9 = 10 -1
Other Nice arrays include {2, 2, 3, 3, 3}, {1, 1, 1, 2, 1, 1} and {0, -1, 1}.
The array {3, 4, 5, 7} is not a Nice array because of the value 7 which requires that the array contains either the value 6 (7-1) or 8 (7+1) but neither of these values are in the array.
Write a function named isNice that returns 1 if its array argument is a Nice array. Otherwise it returns a 0.
If you are programming in Java or C#, the function signature is
int isNice(int a)

Well you can sort the given list and continue from there

Would you please post the function to be aware of what you mean. Thanks

you don’t know how to sort an array? Then building this function becomes really difficult

maybe the language has a built in sort function? otherwise, search for sorting algorithms.

You shouldn’t ask others to do the work for you.

A simple search will return a great number of helpful resources- try it.
