What are the criteria for selecting an algorithm?
All algorithms must satisfy the following criteria: Zero or more input values. One or more output values. Clear and unambiguous instructions.

How do I find the best sorting algorithm?
To choose a sorting algorithm for a particular problem, consider the running time, space complexity, and the expected format of the input list. Stable? *Most quicksort implementations are not stable, though stable implementations do exist. When choosing a sorting algorithm to use, weigh these factors.
How characteristics of algorithms are satisfied in a chosen algorithm?
Characteristics of an Algorithm Each of its steps (or phases), and their inputs/outputs should be clear and must lead to only one meaning. Output − An algorithm should have 1 or more well-defined outputs, and should match the desired output. Finiteness − Algorithms must terminate after a finite number of steps.
What does selection algorithm mean?
In computer science, a selection algorithm is an algorithm for finding the kth smallest number in a list or array; such a number is called the kth order statistic. This includes the cases of finding the minimum , maximum , and median elements.
What is the simplest sorting algorithm?
The simplest sorting algorithm is bubble sort. The bubble sort works by iterating down an array to be sorted from the first element to the last, comparing each pair of elements and switching their positions if necessary. This process is repeated as many times as necessary, until the array is sorted.
Is merge sort algorithm a stable sorting algorithm?
Merge sort is an algorithm based on the divide and conquer paradigm which was invented by John von Neumann in the year 1945. It is a stable but not an in-place sorting algorithm. A stable sorting algorithm is the one where two keys having equal values appear in the same order in the sorted output array as it is present in the input unsorted array.
How do you merge sort?
Conceptually, merge sort works as follows in recursive fashion: Divide the unsorted list into two sublists of about half the size Sort each of the two sublists Merge the two sorted sublists back into one sorted list
