weekend planning - easy tree level algorithms

July 28, 2018

Introduction

It is time for me to plan to work on easy level tree algorithms. Here is the link and I use it to find all easy level tree algorithms I plan to work on this Saturday.

Over ten tree algorithms

I like to write down every easy level tree algorithm by name. I am planning to work on those algorithm today.

Easy level algorithms I completed: 687, 110, 572, 2235, 101, 671, 543, 108, 563, 100, 538, 606, 226, 104, 872, 617.

Easy level algorithms for me to work on:
111, 112, 501, 437, 589, 270, 700, 429, 257, 107, 590, 404, 559, 653, 637, 669

687 Longest Univalue Path 32.7% Easy 111 Minimum Depth of Binary Tree 33.9% Easy 112 Path Sum 35.5% Easy 501 Find Mode in Binary Search Tree 37.8% Easy 110 Balanced Binary Tree 38.9% Easy 572 Subtree of Another Tree 40.3% Easy 437 Path Sum III 40.3% Easy 235 Lowest Common Ancestor of a Binary Search Tree 40.6% Easy 101 Symmetric Tree 41.0% Easy 589 N-ary Tree Preorder Traversal 41.2% Easy 270 Closest Binary Search Tree Value 41.3% Easy 671 Second Minimum Node In a Binary Tree 42.1% Easy 700 Search in a Binary Search Tree 42.1% Easy 429 N-ary Tree Level Order Traversal 42.4% Easy 257 Binary Tree Paths 42.4% Easy 107 Binary Tree Level Order Traversal II 43.2% Easy 543 Diameter of Binary Tree 45.2% Easy 108 Convert Sorted Array to Binary Search Tree 45.7% Easy 563 Binary Tree Tilt 46.9% Easy 590 N-ary Tree Postorder Traversal 46.9% Easy 404 Sum of Left Leaves 47.9% Easy 100 Same Tree 48.2% Easy 538 Convert BST to Greater Tree 48.8% Easy 559 Maximum Depth of N-ary Tree 49.4% Easy 606 Construct String from Binary Tree 50.2% Easy 653 Two Sum IV - Input is a BST 50.3% Easy 226 Invert Binary Tree 54.4% Easy 104 Maximum Depth of Binary Tree 56.2% Easy 637 Average of Levels in Binary Tree 56.3% Easy 669 Trim a Binary Search Tree 58.1% Easy 872 Leaf-Similar Trees 65.0% Easy 617 Merge Two Binary Trees 68.1% Eas
