The function f(s,ch) gets a strings and a character ch. Then it returns a string that is similar to s but does NOT have the character ch. If ch does not appear in s then the result string is equal to s. Example: f('abacadaeafaga', 'a')=='bcdefg' f('abacadaeafaga','A')=='abacadaeafaga'

Problem: Substring Pattern Matching Input: A text string t and a pattern string p Output: Does t contain the pattern p as a substring, and if so, where? For example: with t= abaababbaba, p = abba, your function should return 5. int findmatch(char *p, char *t) { int plen = strlen(p); // len of string int tlen = strlen(t); // len of string t //TODO: your code } Analyze your algorithm: what is the big O?

Can you use Python programming language to to this question? Thanks

Ex. 8.4) The following functions are all intended to check whether a string contains any lowercase letters, but at least some of them are wrong. For each function, describe what the function actually does (assuming that the parameter is a string).

For each function, describe what it actually does when called with a string argument. If it does not correctly check for lowercase letters, give an example argument that produces incorrect results, and describe why the result is incorrect. # 1 def any_lowercase1(s):     for c in s:          if c.islower():               return True          else:               return False # 2 def any_lowercase2(s):     for c in s:          if 'c'.islower():               return 'True'          else:               return 'False' # 3 def any_lowercase3(s):     for c in s:          flag = c.islower()     return flag # 4 def any_lowercase4(s):     flag = False     for c in s:          flag = flag or c.islower()     return flag # 5 def any_lowercase5(s):     for c in s:          if not c.islower():               return False     return True The code and its output must be explained technically whenever asked. The explanation can be provided before or after the code, or in the form of code comments within…

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++.

4. Complete the function show_upper. This function takes one parameter - a string (s). It should return a string made up of all the upper-case characters in s. For example, if s is “aBdDEfgHijK” then show_upper should return “BDEHK”. It should return the upper-case string - not print it. Do not change anything outside show_upper.
