Skew trees are binary trees where each node has at most one child. For n nodes, there are n! possible binary trees.

• Skew trees are binary trees where each node has at most one child.

• For a tree with 4 nodes, all possible binary trees can be drawn by arranging the nodes in different orders.

• Generalizing for n nodes, there are n! possible binary trees that can be drawn.

A binary tree with N nodes has N-1 links.

• A binary tree with N nodes will have N-1 links connecting the nodes.

• This can be proven using the formula for the number of edges in a tree: E = N-1.

• For example, a binary tree with 4 nodes will have 3 links connecting the nodes.

Yes, I have used threaded trees in my lifetime.

• Threaded trees are binary trees in which every node has a thread (or a link) to its inorder successor or predecessor.

• They are used to optimize tree traversal algorithms, as they eliminate the need for stack or recursion.

• Threaded trees can be used for efficient searching, insertion, and deletion operations.

• Example: In a threaded binary search tree, the threads can be used to quickly find the inorder predecessor or successor of a g...read more

Yes, I am interested in List of user interface related software.

• I am familiar with various UI design tools such as Sketch, Figma, and Adobe XD.

• I have experience in developing UI using frameworks like React and Angular.

• I am also interested in exploring emerging UI technologies like voice and gesture-based interfaces.

Pascal is a strongly typed language with built-in data types, while C is a weakly typed language with pointers and manual memory management.

• Pascal has built-in data types, while C requires manual declaration and definition of data types

• Pascal is strongly typed, while C is weakly typed

• C has pointers and manual memory management, while Pascal does not

• Pascal has a simpler syntax and is easier to learn, while C is more complex and powerful

• C is widely used in systems programming, ...read more

The algorithm converts an m-ary tree to a 2-ary tree.

• Start with the root of the m-ary tree

• For each child of the root, create a new node in the 2-ary tree and make it the left child of the root

• For each remaining child of the root, create a new node in the 2-ary tree and make it the right sibling of the previously created node

• Recursively apply the same process to each child of the root

Yes, I am interested in working in GUI.

• I have experience in designing and developing user interfaces.

• I am proficient in using tools like Adobe XD, Sketch, and Figma.

• I enjoy creating intuitive and visually appealing interfaces that enhance user experience.

Strongly typed refers to programming languages that enforce strict data type checking.

• Variables must be declared with a specific data type

• Operations on variables must be compatible with their data type

• Errors will be thrown if there is a type mismatch

• Examples of strongly typed languages include Java, C++, and Swift

ADB commands are used to interact with Android devices from a computer.

• ADB stands for Android Debug Bridge.

• Some common ADB commands are: adb devices, adb install, adb uninstall, adb shell, adb logcat, adb push, adb pull.

• ADB commands can be used to debug apps, install/uninstall apps, access device shell, transfer files, etc.

Sanity and Smoke are types of testing in software QA.

• Smoke testing is a quick test to check if the build is stable enough for further testing.

• Sanity testing is a subset of regression testing and checks if the critical functionalities of the application are working after changes.

• Smoke testing is done before sanity testing.

• Smoke testing is a high-level test while sanity testing is a low-level test.

• Smoke testing is also known as build verification testing.

• Sanity testing is also ...read more
