Merge sort code using recursion in c++
Web31 mrt. 2024 · The algorithmic steps for implementing recursion in a function are as follows: Step1 - Define a base case: Identify the simplest case for which the solution is known or trivial. This is the stopping condition for the recursion, as it prevents the function from infinitely calling itself. WebCHARACTERISTICS of Merge Sort: 1. It is based on the divide and conquers paradigm. 2. It is a comparison-based sorting technique. 3. Merge sort is faster than the insertion sort …

Web9 nov. 2014 · 2 Answers. In merge (), you call malloc () twice with no corresponding calls to free (). That can't be good for your memory consumption! When computing the average of two values, don't do q = (p+r)/2, because that is vulnerable to overflow. Instead, write it as q = p + (r - p) / 2. merge is a called recursively several times.
