Iteration vs. recursion: what do these terms really mean?
Sep 14, 2017 · One can remove any recursion using an explicitly programmed "call stack", as you say, but it's hardly iterative and non-recursive now. Apart from the extreme cases (explicit recursion vs …
Iterative and/or tail-recursive implementations of merge sort?
3 I recently learned how to implement merge-sort, using a standard recursive algorithm. Can the algorithm be implemented in a way that allows for a tail-recursive implementation? Can it be …
Performance of Recursive vs Iterative Solution to "Maximum Depth of a ...
Mar 10, 2020 · There are two solutions to this question - the recursive solution and the iterative / breadth-first traversal solution. My question is in regards to the memory requirements of each …
time complexity - Why are loops faster than recursion? - Computer ...
May 1, 2016 · Looks are only faster than recursion in languages that implement them poorly. In a language with proper Tail Recursion, recursive programs can be translated into loops behind the …
Induction to prove equivalence of a recursive and iterative algorithm ...
Using induction how do you prove that two algorithm implementations, one recursive and the other iterative, of the Towers of Hanoi perform identical move operations? The implementations are as foll...
Differences between DFS based cycle detection algorithms
It seems to me that the difference between grey nodes as in 2. and stack nodes is that grey nodes are "recursive stack" nodes (i.e. nodes in the stack of the recursive calls if DFS is implemented recursively)
Technique for converting recursive DP to iterative DP
Nov 26, 2020 · The title is misleading in the sense that dynamic programming can use either recursive method or iterative method. The correct title should be "How to convert DP using recursive method to …
How does DNS work if there is no recursive querying?
The computer first asks a local domain name server (DNS) what the IP address of this website is. If it can't find it, it then asks the root server, etc. This is recursive querying. How does DNS work if there …
algorithms - Which is better ? Iterations or Recursions? - Computer ...
Jan 12, 2019 · I've heard that any algorithm using iterations can be changed into one that uses recursions and vice-versa. But which type of repetition is preferable for minimum amount of …
algorithms - Are recursion and a stack equivalent in terms of ...
Aug 28, 2021 · I assume new_stack = temp_stack makes a copy of temp_stack? While that's a valid solution (+1), using a "stack of stacks" not only blows time complexity up, but also makes space …
