Question: Given a string S (input consisting) of "*' and '#. The length of the string is variable. The task is to find the minimum number of "*' or '#' to make it a valid string. The string is considered valid if the number of "*' and '#' are equal. The " and '#' can be at any position in the string. Note: The output will be a positive or negative integer based on number of and '#' in the input string. • (*>#): positive integer • (#>*): negative integer • (#=*): 0 Example 1: Input 1: • ###*** -> Value of S Output: 0 ➜ number of* and # are equal
