They will meet again after the starting point at a distance of LCM(x, y).

• The distance at which they will meet again is the least common multiple (LCM) of their speeds.

• For example, if A is running at a speed of 4 m/s and B is running at a speed of 6 m/s, they will meet again after 12 meters.

• Another example, if A is running at a speed of 3 km/hr and B is running at a speed of 5 km/hr, they will meet again after 15 km.

The wire crafted into a circle will have the minimum area.

• The circle has the smallest perimeter to area ratio compared to the equilateral triangle and square.

• The formula for the area of a circle is A = πr^2, where r is the radius.

• For the equilateral triangle, the formula is A = (√3/4) * s^2, where s is the side length.

• For the square, the formula is A = s^2, where s is the side length.

BST Tree is a binary tree data structure where each node has at most two children, with left child nodes being less than the parent node and right child nodes being greater.

• BST Tree stands for Binary Search Tree.

• In a BST Tree, the left subtree of a node contains only nodes with keys less than the node's key, and the right subtree contains only nodes with keys greater than the node's key.

• Example: Inserting values 5, 3, 7, 1, 4 into a BST Tree would result in a tree with root n...read more
