A Prime Array is an array which doesn't contain a pair of numbers whose product is a square of an integer.
For eg [1,2,3] is a Prime Array but [1,2,4] is not.
Explanation : 1*4 gives 4 which is square of 2.
Given an array of integers determine the minimum number of operations to convert the array to a Prime array.
NOTE: An operation consists of either increasing or decreasing any element of the array by 1 but the element should always be positive.
Constraints: Length of array <=100
1 <=Each integer in array <=1000000
Eg. Array => [1,1,2]
Minimum operations to convert [1,1,2] to [1,2,3] is 2.
