Convert a numeric string to an integer using a for loop and ASCII arithmetic, and transform vowels to indices while collecting digits and counting vowels.
Apply a recursive traversal from the root to sum all node values into a global variable, visiting left then root then right, yielding six for the sample tree.
Explore how binary search trees insert nodes and perform in-order traversal to produce sorted output, illustrated with a BST rooted at four and nodes two, six, one, three, five, seven.
Explore matrix manipulation by performing a spiral order traversal on a two-dimensional vector using a solution class, returning an array of numbers.
You may be new to Data Structure or you have already Studied and Implemented Data Structures but still you feel you need to learn more about Data Structure in detail so that it helps you solve challenging problems and used Data Structure efficiently.
This 8 hours of course covers each topic in greater details, every topic covered will improve your Problem Solving and Analytical Skills. Every Data Structure and algorithm is discussed, analyzed and implemented with a Practical line-by-line coding .
About Instructor
I am the Instructor of this course, I am a passionate young software engineer with a penchant for both practising and teaching algorithms and data structures. With a focus on practical application and clear explanation, I aim to demystify these fundamental concepts for learners of all levels. I know how to present the topic so that it's easy to grasp for students. Join me on a journey to master the building blocks of efficient software development!
