Given a text and a wildcard pattern of size N and M respectively, implement a wildcard pattern matching algorithm that finds if the wildcard pattern is matched with the text. The matching should cover the entire text not partial text.

The wildcard pattern can include the characters ‘?’ and ‘*’

 ‘?’ – matches any single character 
 ‘*’ – Matches any sequence of characters(sequence can be of length 0 or more)

2. Next Greater Element

Asked in companies
FlipkartAmazonGroww

You are given an array 'a' of size 'n'.



The Next Greater Element for an element 'x' is the first element on the right side of 'x' in the array, which is greater than 'x'.


If no greater elements exist to the right of 'x', consider the next greater element as -1.


For example:
Input: 'a' = [7, 12, 1, 20]

Output: NGE = [12, 20, 20, -1]

Explanation: For the given array,

- The next greater element for 7 is 12.

- The next greater element for 12 is 20. 

- The next greater element for 1 is 20. 

- There is no greater element for 20 on the right side. So we consider NGE as -1.
