Please do in python. Given an array of integers, create a 2-dimensional array where the first element is a distinct value from the array and the second element is the value’s frequency within the array. Sort the resulting array descending by frequency. If multiple values have the same frequency, they should be sorted ascending. Example: arr = [3,3,1,2,1]There are two values, 3&1 each within frequency of 2, and one value 2 with a frequency of 1: [[3,2], [1,2], [2,1]] Sort the 2-dimensional descending by frequency: [[3,2], [1,2], [2,1]] Sort the 2-dimensional array descending by values with matching frequencies [[1,2], [3,2], [2,1]]
