In Java, develop a pseudocode algorithm to build an expression tree from a prefix expression.

In Java: DRAW the binary expression tree for the following: g + h - i + j - k + m

Do you have any idea what makes minimum spanning trees so special? The c language is taken for granted.

Recursive definitions Give the recursive definition for the following languages: (a) L2a = {w = {0, 1}* |w has 00 as a substring} (b) L₁₁ = {w= {0,1}* |w all strings with alternating O's and 1's} (c) L2c = {w = {0, 1}* |w has a equal number of 0's and 1's}

Implement the pre-order tree traversal algorithm in C++. This program should use the following binary tree (see image) and display the pre-order tree traversal of the nodes’ values. Feel free to write this iteratively or recursively. Also, explain how it works and how a new tree could be provided to the code. PS: make sure that the logic of the program is correct, meaning that it can work well with different binary trees. I would like to change the tree input to the pre-order traversal function. The program should work errorless and display the result correctly. No need to code it to read the user input, however, provide instructions on how a new tree can be defined in this program to check if the program works fine with different trees.

Explore the concept of Binary Expression Trees and their role in evaluating mathematical expressions. How can you construct and evaluate expressions using binary expression trees?

write a java code: Consider the following expression BNF: ::= * | / | :== + | - | ::= { }| :: 0|1|2|3|4|5|6|7|8|9 Using recursive descent, and only recursive descent, scan expressions that adhere to this BNF to build their expression tree; write an integer valued function that scans the tree to evaluate the expression represented by the tree. Input: A numeric expression adhering to this BNF. Output: Some representation of the expression tree. The result of evaluating the expression. write a java code for it.

In C++ when learning binary search trees, how can they be implemented into projects, with real actual examples?
