Coding String
Input You are given a template in which you need to implement a function whose signature is given below. C int findWordInAGrid(char grid[128][128], int m, int n, char word[32]) /* return 0 for false, 1 for true. */ C++ bool findWordInAGrid(char grid[128] ... abc abedhi efgh Output: The output of the above example should be: abc: true abedhi: true efgh: false Constraints 1 ≤ m,n ≤ 100

Finding best time complexity
$\begin{align*} & a[n] = \{x_1,x_2,x_3,x_4,....,x_n\} \text{ is an array of integers where } n,x_i > 0. \\ & A = \left [ \text{min}\left ( x_i,x_j \right ) \right ] \cdot \left ( j-i \right ) \text{ where } j > i \text{ and } i,j \leq n \\ & \text{What is the best time complexity to find out the value of } A_{\bf max} \; ? \end{align*}$

Zigzag Arrangement
Given an array with possible repeating elements you have to rearrange such that elements are alternatively decreasing and increasing (strict increase/decrease). For example, suppose the given array is 1 1 2 3 4 5 one possible answer would be 2 1 3 1 5 4. Assumption: Solution do exist for any given input. Hint: Try to avoid sorting.

Wine Bottle
A bad king has a cellar of 1000 bottles of delightful and very expensive wine. A neighboring queen plots to kill the bad king and sends a servant to poison the wine. Fortunately (or say unfortunately) the bad king's guards catch the servant after he has only poisoned one ... in mind of the king, how will he be able to do so ? (of course he has less then 1000 prisoners in his prisons)
