leet-go

A small collection of Go solutions for common coding interview and algorithm problems. Each problem lives in its own folder with a single main.go entry point.

Structure

Each folder contains a standalone Go program:

• 3sum/
• 3sumClosest/
• addTwoNums/
• averageOfLevels/
• backspaceCompare/
• binarySearch/
• binaryTreePaths/
• characterReplacement/
• convert1Dinto2Darray/
• countElemGTPA/
• deleteDuplicates/
• diagonal-difference/
• EncodeDecode/
• findDisappearedNumbers/
• findDuplicates/
• findMaxAverage/
• fruitIntobaskets/
• groupAnagrams/
• hasCycle/
• hasDuplicate/
• invertTree/
• isSameTree/
• isSubsequence/
• jumpingOnClouds/
• lengthOfLongestSubstring/
• longestPalindrome/
• majorityElement/
• maxDepth/
• meetingRooms/
• mergeTrees/
• mergeTwoLists/
• middleNode/
• minDepth/
• mini-max-sum/
• minSubArrayLen/
• missingNumber/
• move-zeros/
• nextGreatestLetter/
• palindromeLinkedlist/
• pathSum/
• permutationInString/
• plusMinus/
• productExceptSelf/
• rangeSumQuery/
• removeDuplicates/
• removeElements/
• repeatedString/
• reverseLinkedList/
• sortColors/
• sortedSquares/
• staircase/
• subarraySumEqualsK/
• subtree/
• sudoku/
• topKFrequent/
• twoSum/
• water-container/

Prerequisites

• Go 1.20+ (any recent Go version should work)

Run a solution

From the repo root, run any problem by pointing go run at its folder:

go run ./twoSum

If a solution reads from stdin or prints output, follow the prompts or pipe input as needed.

Update the folder list

Run the helper script to refresh the auto-generated folder list in this README:

bash ./scripts/update-readme.sh

Notes

These are standalone practice solutions. There is no shared package or test harness at the repo root.
