The first line of input contains an integer T denoting the no of test cases. Then T test cases follow. Each test case contains two lines. The first line of each test case contains an integer N. Then in the next line are N space separated values of the array A. Output: For each tes...

But for DataFrame, we will need a two dimensional array. To create a two dimensional array, we have two different approaches: Using the arange() and reshape(): We can use both these methods one after another to generate a range of values and place them in a proper shape. Here is a ...
