Linux !#bin/bash NOT JAVA OR C++. I NEED LINUX SCRIPT Word Separator Write a program that accepts as input a sentence in which all of the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example the string “StopAndSmellTheRoses.” would be converted to “Stop and smell the roses.”
def swap_text(text): Backstory: Luffy wants to organize a surprise party for his friend Zoro and he wants to send a message to his friends, but he wants to encrypt the message so that Zoro cannot easily read it. The message is encrypted by exchanging pairs of characters. Description: This function gets a text (string) and creates a new text by swapping each pair of characters, and returns a string with the modified text. For example, suppose the text has 6 characters, then it swaps the first with the second, the third with the fourth and the fifth with the sixth character. Parameters: text is a string (its length could be 0)Return value: A string that is generated by swapping pairs of characters. Note that if the Examples: swap_text ("hello") swap_text ("Party for Zoro!") swap_text ("") def which_day(numbers): → 'ehllo'→ 'aPtr yof roZor!' → '' length of the text is odd, the last character remains in the same position.

• R7.17Consider the following code that repeats a C++ string three times. string a = "Hello"; string b = a + a + a; Suppose s is a C string, and t is declared as char t[100]; Write the equivalent code for C strings that stores the threefold repetition of s (or as much of it as will fit) into t.

The function returns true if string s is changed, and otherwise, it returns false. bool replace_strings(string& s, with new substring a const string& old_string, const string& new_string) Write a test program that prompts the user to enter three strings, i.e., s, old_string, and new_string, and display the replaced string.
Homework 10-2 Programming Challenge: 12 - Password Verifier Use the string data type. Do not use arrays of type char or any functions in the old "C String" libraries. Six characters? Seriously? Set the minimum password length to twelve characters. We will also require that the password not contain any space characters. In addition to the requirement that the password contain at least one upper case letter, one lower case letter, and one digit, add the additional requirement that the password contain at least one "special" character. We will consider any character that is printable, not alphanumeric, and not a space character to be "special." That includes punctuation, but may include additional non-punctuation characters. Unfortunately at our level of C++ it's more or less impossible for us to actually test passwords like Señor_99 but the ñ (with a tilde) would count as a special character using our rules. Write functions to complete these tasks as appropriate.

String Pair // Problem Description // One person hands over the list of digits to Mr. String, But Mr. String understands only strings. Within strings also he understands only vowels. Mr. String needs your help to find the total number of pairs which add up to a certain digit D. // The rules to calculate digit D are as follow // Take all digits and convert them into their textual representation // Next, sum up the number of vowels i.e. {a, e, i, o, u} from all textual representation // This sum is digit D // Now, once digit D is known find out all unordered pairs of numbers in input whose sum is equal to D. Refer example section for better understanding. // Constraints // 1 <= N <= 100 // 1 <= value of each element in second line of input <= 100 // Number 100, if and when it appears in input should be converted to textual representation as hundred and not as one hundred.
