Coder-Stat Dataset Overview The Coder-Stat dataset is a collection of programming-related data, including problem IDs, programming languages, original statuses, and source code snippets. This dataset is designed to assist in the analysis of coding patterns, error types, and performance metrics. Dataset Details Modalities Tabular: The dataset is structured in a tabular format. Text: Contains text data, including source code snippets.… See the full description on the dataset page: https://huggingface.co/datasets/prithivMLmods/Coder-Stat.

1 2 3<H1>Binary Tree Intersection And Union</H1>4 5<p>6Given two binary trees, we consider the “intersection” and “union” of them.7Here, we distinguish the left and right child of a node when it has only one8child. The definitions of them are very simple. First of all, draw a complete9binary tree (a tree whose nodes have either 0 or 2 children and leaves have10the same depth) with sufficiently large depth. Then, starting from its root,11write on it a number, say, 1 for each position of first tree, and draw different12number, say, 2 for second tree. The “intersection” of two trees is a tree with13nodes numbered both 1 and 2, and the “union” is a tree with nodes numbered14either 1 or 2, or both. For example, the intersection of trees in Figures 1 and152 is a tree in Figure 3, and the union of them is a tree in Figure 4.16</p>17 18<center>19<img src="https://judgeapi.u-aizu.ac.jp/resources/images/IMAGE1_1001">20</center>21 22<p>23A node of a tree is expressed by a sequence of characters, “(,)“. If a node24has a left child, the expression of the child is inserted between ’(’ and ’,’.25The expression of a right child is inserted between ’,’ and ’)’. For exam-26ple, the expression of trees in Figures 1 and 2 are “((,),(,))“ and “((,(,)),)“,27respectively.28</p>29 30<H2>Input</H2>31 32<p>33Each line of the input contains an operation. An operation starts with a34character which specifies the type of operation, either ’i’ or ’u’: ’i’ means35intersection, and ’u’ means union. Following the character and a space,36two tree expressions are given, separated by a space. It is assumed that371 <= #nodes in a tree <= 100, and no tree expression contains spaces and38syntax errors.
