You are given an array 'ARR' of distinct positive integers. You need to find all numbers that are in the range of the elements of the array, but not in the array. The missing elements should be printed in sorted order.

Example:

If the given array is [4, 2, 9] then you should print "3 5 6 7 8". As all these elements lie in the range but not present in the array.

A prime adjacent is a number that is adjacent to two prime numbers. Two numbers are considered adjacent to each other if the absolute difference between them is 1.

For Example:

4 is a prime adjacent because it is adjacent to the numbers 3 and 5, which are prime numbers.

Your task is to find out if the number given to you is prime adjacent or not.

You are given a 'N' * 'N' maze with a rat placed at 'MAZE[0][0]'. Find and print all paths that rat can follow to reach its destination i.e. 'MAZE['N' - 1]['N' - 1]'. Rat can move in any direc­tion ( left, right, up and down).

Value of every cell in the 'MAZE' can either be 0 or 1. Cells with value 0 are blocked means the rat can­not enter into those cells and those with value 1 are open.

Given a string 'S', you are supposed to return the number of distinct substrings(including empty substring) of the given string. You should implement the program using a trie.

Note :

A string ‘B’ is a substring of a string ‘A’ if ‘B’ that can be obtained by deletion of, several characters(possibly none) from the start of ‘A’ and several characters(possibly none) from the end of ‘A’. 

Two strings ‘X’ and ‘Y’ are considered different if there is at least one index ‘i’  such that the character of ‘X’ at index ‘i’ is different from the character of ‘Y’ at index ‘i’(X[i]!=Y[i]).
