OORWIN TEST
I.Given list of n integers, insert one of
the operators (+, -, *) between pair of consecutive integers such that the
result obtained after calculating the resulting expression should be divisible
by 101. Given lists of integers for which an answer exists if answers do not
exist print error message.
For
Interview Team, below are the inputs for which answers exists
Sample Input
3
22
79 21
Sample Output
22*79-21
or
Explanation
Solution 1: 22*79-21=1717, where 1717/101=17, so it
is perfectly divisible by 101.
Solution
2: 22+79*21= (22+79) *21=2121, which is also divisible by 101.

III.Find an element of the array such that the
sum of all elements to the left is equal to the sum of all elements to right.
For instance, given the array arr= [5,6,8,11], 8 is between to subarrays the
sum to 11. If your starting array is [1], that element satisfies the rule as
left and right sum to.
You
will be given arrays of integers and must determine whether there is an element
that meets the criterion.
Sample Input
3
1
2 3
Sample Output
NO
IV.Given an array of integers, find and print
the maximum number of integers you can select from the array such that the
absolute difference between any two of the chosen integers is less than or
equal to 1. For example, if your array is a= [1,1,2,2,3,3,4,4,5,5,5], you can
create two subarrays meeting the criteria: [1,1,2,2] and [4,4,5,5,5]. The
maximum length of sub array has 5 elements;
Sample
Input:
6
4
6 5 3 3 1
Sample
Output
3
We
choose the following multiset of integers from the array: [4,3,3}.
Each
pair in the multiset has an absolute difference <=1 (i. e|4-3|=1, and
|3-3|=0), so we print the number of chosen integers 3, as our answer.
