Problem: 700. Search in a BST
BST rule makes searching super simple
If val<root→go left
If val>root→go right
If equal→found it!
Time: O(log N) for balanced BST
Space: O(1)

Legacy random function 'rand()' is not recommended due to its limited range & thread safety issues.
Mersenne Twester algo on the other hand is way safer & better

Passing the size of every dimension of a multi-dimensional array independently to a function is a bit time consuming.
Herein below an example of passing a 2d C-style array to function by merely passing the array itself:

A simple example of how 'variadic templates' works by enabling a function to accept an arbitary number of arguments.
C 17 introduced 'folding expression' which does almost the same.
