Given a sorted array A of size N. The function remove_duplicate takes two arguments . The first argument is the sorted array A[ ] and the second argument is 'N' the size of the array and returns the size of the new converted array A[ ] with no duplicate element.
The first line of input contains T denoting the no of test cases . Then T test cases follow . The first line of each test case contains an Integer N and the next line contains N space separated values of the array A[ ] .
For each test case output will be the transformed array with no duplicates.
Your task to complete the function remove_duplicate which removes the duplicate elements from the array .
1 <= T <= 100
1 <= N <= 104
1 <= A[ ] <= 106
Input (To be used only for expected output) :
2 2 2 2 2
1 2 2
Note:The Input/Ouput format and Example given are used for system's internal purpose, and should be used by a user for Expected Output only. As it is a function problem, hence a user should not read any input from stdin/console. The task is to complete the function specified, and not to write the full code.
