# DCP-428: Minimum Contiguous Subarray Back to All Problems

You are given an array **A** of **N** integers. You have to partition the array into minimum number of partition of contiguous sub-arrays in such a way that every sub-array has **exactly one unique element**. Input: ------ Input starts with an integer **T (1<=T<=20)**, denoting the number of test cases. Each case contains an integer **N (1 ≤ N ≤ 100000)** denoting the number of elements of array A. The next line will contain **N** integers separated by spaces, denoting the elements of the array A. Each of these integers will be in the range of 32 bit signed integer number. Output: ------- For each case of input, output the minimum number sub-arrays formed with above mentioned partition. Sample Input ------------ 2 5 1 2 4 3 5 3 1 1 2 Sample Output ------------- 5 2 Explanation:<br> In sample testcase-1, minimum partition is : 1 | 2 | 4 | 3 | 5 , So minimum sub-arrays formed are 5.<br> In sample testcase-2, minimum partition is : 1 1 | 2 , So minimum sub-arrays formed are 2. Although there could be another valid partition: 1 | 1 | 2 , but sub-arrays formed are 3.
