I had a list of strings and i want to concatenate them but when I am trying this, I getting error stated cannot perform + operation on string type. The list size is 10.

What characters are utilised as delimiters when you supply null as a parameter to the Split method of a string object?

You are not allowed to use any imports. You may not use any lists or list methods. Do not use try-except statements. I included the is-palindrome function down below

Q:  Write regular expression for the following languages.  All strings in which b is never tripled. It means that no words contain the substring bb. All the strings accepting b as second letter. Regular expression that accept only prime numbers. All the strings that start with aa, end with bb, and have alternating substrings ba in between. Language of all those strings with length greater than 3

In C language, Write a function that gets a string containing a positive integer. The function subtracts 1 fromthat integer and puts the obtained value in the string. void str_subtract_one(char* num); For example:- if before we call str_subtract_one(str) we have str==“1997”, then after return str will be “1996”.- if before we call str_subtract_one(str) we have str==“12345678987650”, then after return str will be “12345678987649”.- if before we call str_subtract_one(str) we have str==“100”, then after return str will be “99”. 1. You may assume that the input is always legal, i.e., the string is a positive integer correctly formatted.2. Note that the numbers may be larger than the maximum of int or long. That is, you should not try to convert string to int

In C++

public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string

Please do not use string methods (replace)! Thank you!

Please write regular expression (regex) for strings that contain numbers and commas. Thank you very much
