Given a string of positive number ranging from 0 to 9, the task is to check whether the number is valid pin code or not, by using Python Regular Expression.The valid pin code of India must satisfy the following conditions. It can be only six digits.It should not start with zero.First digit of the pin code must be from 1 to 9.Next five digits of the pin code may range from 0 to 9.Pincode may or may not have one white space. It should allow only one white space, but after three digits. For example, 600064 and 600 064 are valid pincodesSample Input132103Outputtrue

Mahi has a collection of mobile numbers.  His work is to validate them according to the following constraints:It should be of 10 digits.Only numerals are allowed.No leading zeroes.Single space may or may not be available after first 5 digits. Read N number of mobile numbers and classify them as either “VALID” or “INVALID”. Use Python regular expressions to accomplish this task on behalf of Mahi. Sample Input:3944246489056124782a30875312469 Sample Output:ValidInvalidInvalid

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(#=*): 0Example 1:Input 1:###*** -> Value of SOutput :0 ? number of * and # are equal
