Define a function in the Ruby language to take a string as a parameter return that string after removing all spaces from that string.

Write a function in JAVA language that accepts three integer parameters and returns true if two or more of them (integers) have the same rightmost digit. The integers are non-negative. Inside the main function test the function for at least two test cases.

//the language is c++ Implement function to tokenize a string. std::vector<std::string> tokenize(std::string& line) { } int main(){ std::string ts = "This is a string with no commas semicolons or fullstops"; std::vector<std::string> tok = tokenize(ts); for (auto x : tok) { std::cout<<x<<std::endl; } return 0; }

If s and t are strings, then index function (s, t) in C++ or a similar language would be the int that is the value of the function at the ordered pair (s, t). Translate this function into a standard mathematical function specification.

Define a function FilterStr() that takes a string parameter and returns "Acceptable" if the first character and the character at index 3 in the string parameter are the same. Otherwise, the function returns "Unacceptable". Ex: FilterStr("surfing") returns Unacceptable Recall string's at() returns a character at the specified position in the string. Ex: myString.at(3) #include <iostream>#include <string>#include <cctype>using namespace std; /* Your code goes here */ int main() { string input; string output; getline(cin, input); output = FilterStr(input); cout << output << endl; return 0;}

IN JAVA Write a function that takes in user input as a string. For all characters which are numeric, double its value and, if it is two digits, then replace it with the sum of its digits (e.g., 6 → 12 → 3 whereas 3 → 6). For all characters which are in uppercase, replace it with lowercase. For all characters which are in lowercase, replace it with uppercase (e.g., m → M and N → n). The program should keep asking the user to enter strings until they either enter ‘q’ or ‘Q’.

Write a function in Scala programming language that takes a string parameter and returns whether the string starts with "Sc" or not. Test the function for the sample strings "Scala", "Programming", "Science".

Write a function myReverse in PHP language that takes a string parameter and returns the string after reversing it. Also, test the function for some sample strings.

Write a program in C programming language that takes two arguments at the command line, both strings. The program checks to see whether or not the second string is a substring of the first (without using the substr -- or any other library -- function). One caveat: any * in the second string can match zero or more characters in the first string, so if the input were abcd and the substring was a*c, then it would count as a substring. Also, include functionality to allow an asterisk to be taken literally if preceded by a ,円 and a \ is taken literally except when preceding an asterisk.

Write the following function in Lisp: a function that takes one parameter that you can assume to be a symbol named after a day of the week (no need to check it), such as 'monday, and returns the symbol for the next day. For example, (next-day 'tuesday) should return the symbol 'wednesday. Implement this function with a complex conditional.

Develop an algorithm and write a C++ program that counts the letter occurrence in the C-string; make sure you use call by reference to the array of a class with char and count as private member attributes when return from parse function. For the class member methods, provide the public accessor and modifier as well as print functions for the private member attributes. Write a test program that reads a C-string and displays the number of spaces, letters [a-z] [A-Z] and number of numbers [0-9] in the string. In addition to that, you need to output the histogram of the char and count array sorted by the ascii char ascending order. Here is a sample run of the program: <Output; double quote enclosure on string is required in the output> Enter a string: 2024 is coming The number of spaces in "2024 is coming" is 2 The number of letters in "2024 is coming" is 8 The number of numbers in "2024 is coming" is 4 ---- Histogram ---- Char Count space 2 0...

Write a C++ function add_strings that takes two parameters of type string and returns the concatenation of the two parameters.

A function that turns an argument to a string (call it "toString(...)") is a great use of function overloading. In one sentence, why might this be? In one sentence, why should we generally verify the arguments are what we expect when writing a function?
