# Coding Challenge Problems

A repository for me to keep up with coding challenge problems (think: [LeetCode](https://leetcode.com/)) from various sources.

## To-Do

 * Refactor `*Hash` challenge problems to abandon generics in favor of `int` types (because otherwise, binning for floats, etc., is bad news!).

 * More exercises.

 * More languages.

    

Changelog

31 May 2023



    
Beginning of LeetCode, and initial commit of LeetCode/CPP/1TwoSum.cpp.



18 May 2023



    
Modified some Section 8 files to eliminate unnecessary size parameter + updated TODO list above.

    
Later, modified more Section 8 files to rename arr parameter as A.

    
Completed first versions of StringPermutations, ... , and made small edits throughout.

    
Cleaned up repo by deleting .exe files (these never should have been uploaded) + making initial commits of some missed files from yesterday.



17 May 2023



    
In CountDuplicatesUnsorted: Removed unused Min and Max functions.

    
Later, added PairSumUnsorted, PairSumUnsortedHash, PairSumSorted, and SinglePassMaxMin from Udemy's Mastering Data Structures & Algorithms using C and C++ course (link).

    
After finishing the Section 7 algorithms (above), added Print functionality to all.

    

From Section 8, added StringToggleCase, CountConsonantsAndVowels, CountWords, StringReverse, CompareStrings, IsPalindrome, StringCountDuplicates, StringCountDuplicatesHash, StringFindDuplicatesBitwise, and IsAnagram, and the related ToUpperCase and ToLowerCase.

    
Made a small correction to CountDuplicatesUnsortedHash.

    
Eventually: Added a Udemy subdirectory to future-proof the repo.





16 May 2023



    
Initial commit + README.

    
Later, created CPP directory.

    
Later, created + updated versions of FindMissingElementSorted, FindMissingElementSortedStart, FindMissingElementSortedMultiple, FindMissingElementUnsortedHash, FindDuplicatesSorted, CountDuplicatesSorted, CountDuplicatesSortedHash, CountDuplicatesUnsortedHash, and CountDuplicatesUnsorted from Udemy's Mastering Data Structures & Algorithms using C and C++ course (link).
