A program to generate the Fibonacci series up to n terms provided by the user.
Fibonacci series starts with 0 and 1.
Each subsequent number is the sum of the previous two.
Example: For n=5, the series is 0, 1, 1, 2, 3.
Inorder traversal of a binary tree visits nodes in left-root-right order, yielding a sorted sequence for BSTs.
Inorder traversal visits the left subtree, then the root, and finally the right subtree.
For a binary tree: Given nodes A, B, C, where A is the root, B is left child, and C is right child, the order is B, A, C.
Example: For a BST with values 2, 1, 3, the inorder traversal results in [1, 2, 3].
Recursive imple...
This task involves sorting numbers and using binary search to find a specific number in the sorted array.
1. Sort the array: Example - [5, 2, 9, 1] becomes [1, 2, 5, 9].
2. Implement binary search: Start with the middle element and compare it to the target.
3. If the middle element is equal to the target, return its index.
4. If the target is less than the middle element, search the left half.
5. If the target is great...

Find the heavier ball out of 8 using a weighing balance in minimum and maximum attempts.
Divide the balls into 3 groups of 3, 3, and 2.
Weigh the first two groups against each other.
If they balance, the heavier ball is in the third group.
If one group is heavier, weigh two balls from that group against each other.
If they balance, the heavier ball is the remaining one.
If one ball is heavier, that is the answer.

If they don't balance, the heavier ball is in the heavier group. Take two balls from the heavier group and wei...
Use a binary search approach to find the heavier ball among 'n' balls using a weighing balance.
Divide the 'n' balls into two equal groups and weigh them on the balance.
If one group is heavier, repeat the process with that group.
If both groups weigh the same, the heavier ball is among the remaining unweighed balls.
Continue dividing and weighing until the heavier ball is found.

Full selectors are more general and can target multiple levels of descendants, while partial selectors are more specific and target only direct children.
Example of full selector: div p selects all
