Write a program called p3.py. Write a function called validate() that takes a string as input, validates that it is a single letter, and returns the letter in lowercase. Example: validate(“A”) returns a validate(“abc”) returns invalid

Write a program that removes all spaces from the given input. Ex: If the input is: Hello my name is John. the output is: HellomynameisJohn. Your program must define and call the following function. The function should return a string representing the input string without spaces.string RemoveSpaces(string userString) #include <iostream>#include <algorithm>using namespace std; string removeSpaces(string str) { str.erase(remove(str.begin(), str.end(), ' '), str.end()); return str; } /* Define your function here */ int main() {string str; str = removeSpaces(str); cout << str << endl; /* Type your code here. Your code must call the function. */ return 0;} Please help me with this problem using c++.

Using Python write a string-comparison function named strNcompare that compares up to n characters of a string s1 with the other string s2. The function must return 0, -1, or 1 if the first n-character portion of s1 is equal to, less than, or greater than the corresponding first n-character portion of s2, respectively. (1) You must use the following function definition: def strNcompare(s1, s2, n): (2) String comparison must be case-insensitive. For example, the strNcompare function must return 0 for the s1 value of ‘tommy’ and the s2 value of ‘TOMMY’. (3) You should not use a loop such as the while loop and the for loop inside the strNcompare function.    Then write a Python program that receives two words and the number of characters for comparison, calls the strNcompare function, and then shows the result. Your program keeps doing this until the user enters the value of -1.     Your program displays the message ‘String comparison [1(play), -1(quit)]: ’ and receives the value 1 or -1…

Write a program to enter two strings from the user using function cin.getline and then appends string two with string one separated by a blank space. Sample Input: C++ is a good programming Language. Arrays are very integral part of this language. Sample Output: C++ is a good programming Language. Arrays are very integral part of this language.
