Question
Need help with this c++ problem
Use recursion to implement a function: find(s, t) that tests whether the string t is
contained in the string s. For instance, calling the function like this:
find("Mississippi", "sip")
returns true.
You must use recursion to complete this, not loops; you obviously may not use the
string find() member function either. Here's the basic strategy:
• If the text starts with the string you want to match, then you are done.
• If the string s is smaller than the string t, you are also done.
• If not, check the sentence without the first character.

- Please use C++ and make sure it's for a sorted array Write a function, remove, that takes three parameters: an array of integers,the number of elements in the array, and an integer (say, removeItem). Thefunction should find and delete the first occurrence of removeItem in thearray. If the value does not exist or the array is empty, output an appropriatemessage. (Note that after deleting the element, the number of elements inthe array is reduced by 1.) Assume that the array is sorted.arrow_forwardPlease answer quick in pythonarrow_forwardI need the code from start to end with no errors and the explanation for the code ObjectivesJava refresher (including file I/O)Use recursionDescriptionFor this project, you get to write a maze solver. A maze is a two dimensional array of chars. Walls are represented as '#'s and ' ' are empty squares. The maze entrance is always in the first row, second column (and will always be an empty square). There will be zero or more exits along the outside perimeter. To be considered an exit, it must be reachable from the entrance. The entrance is not an exit.Here are some example mazes:mazeA7 9# # ###### # # ## # # #### # ## ##### ## ########## RequirementsWrite a MazeSolver class in Java. This program needs to prompt the user for a maze filename and then explore the maze. Display how many exits were found and the positions (not indices) of the valid exits. Your program can display the valid exits found in any order. See the examples below for exact output requirements. Also, record…arrow_forward
- Write a function lis_rec(arr) that outputs the length of the longest increasing sequence and the actual longest increasing sequence. This function should use divide and conquer strategy to the solve the problem, by using an auxiliary function that is recursive. For example, one possibility is to define a recursive function, lis_rec(arr, i, prev), that takes the array arr, an index i, and the previous element index prev of LIS (which is part of the array arr before index i), and returns the length of the LIS that can be obtained by considering the subarray arr[i:]. Write a dynamic programming version ofthe function, lis_dp(arr), that outputs the length of the longest increasing sequence and the actual longest increasing sequence by using a table to store the results of subproblems in a bottom-up manner. Test the performance of the two functions on arrays of length n = 100, 500, 1000, 5000, 10000. Compare the running times and memory usage of the two functions.arrow_forwardIn c++, please! Thank you! Write a void function SelectionSortDescendTrace() that takes an integer array and sorts the array into descending order. The function should use nested loops and output the array after each iteration of the outer loop, thus outputting the array N-1 times (where N is the size). Complete main() to read in a list of up to 10 positive integers (ending in -1) and then call the SelectionSortDescendTrace() function. If the input is: 20 10 30 40 -1 then the output is: 40 10 30 20 40 30 10 20 40 30 20 10 The following code is given: #include <iostream> using namespace std; // TODO: Write a void function SelectionSortDescendTrace() that takes// an integer array and the number of elements in the array as arguments,// and sorts the array into descending order.void SelectionSortDescendTrace(int numbers [], int numElements) { } int main() { int input, i = 0; int numElements = 0; int numbers [10]; // TODO: Read in a list of up to 10 positive…arrow_forwardPlease use C++ and make sure it's for a sorted array Write a function, removeAll, that takes three parameters: an array of integers,the number of elements in the array, and an integer (say, removeItem).
