Kotlin | Operations on String Array: Here, we are going to learnhow to perform read, traverse, reverse and sorting operations on a string array in Kotlin programming language?Submitted byIncludeHelp, on May 03, 2020 Kotlin - Read, traverse, reverse, and sort string array ...
Let's run this algorithm another time, but sorting in decreasing order (: → Reply cgy4ever 9 years ago, # | ← Rev. 2 +55 What can you reverse? Adjacent elements? Then that is the number of [inversion](https://en.wikipedia.org/wiki/Inversion_(discrete_mathematics)). Any contin...
For sorted arrays, you can combine sorting with slicing to reverse the order: import numpy as np # Create a sorted array arr = np.array([1, 2, 3, 4, 5]) # Sort in descending order reversed_arr = np.sort(arr)[::-1] print(reversed_arr) # Output: [5 4 3 2 1] ...
Comparableinterface. (The natural ordering is the ordering imposed by the objects' owncompareTomethod.) This enables a simple idiom for sorting (or maintaining) collections (or arrays) of objects that implement theComparableinterface in reverse-natural-order. For example, supposeais an array of ...
In the Sort Options dialogue box, select Sort left to right for the horizontal sorting. Press OK. The Sort dialogue box will pop up. In the Sort by dialogue box, input the helper row’s row number which is Row 6. In the Order dropdown, select Largest to Smallest. Press OK. This wi...

B4: C8 is the array that will be reversed/sorted. ROW(B4:B8) will give the row number of product. -1 is for sorting the data in descending order. To apply this formula, follow the steps below. Steps: Let’s create a header column for reversed ordered data like this. In cell E4,...
