Complete the find_string(sentence, string_to_find) function that takes two string parameters, namely sentence and string_to_find. This function should return the number of times that the parameter, string_to_find, appears in the sentence.

We are given a function countWordOccurrences that takes two string parameters sentence and word."Sentence" is a string made up of multiple words separated by spaces.We have to find how many times 'word' occurs in the given 'sentence'.The 'word' should be an exact match.Note: The case (uppercase/lowercase) of the letters in the word does NOT matter.InputFirst line contains space separated series of words which represents the string "sentence".Second line contains a single word "word".Constraints1 ≤ length(sentence), length(word) ≤ 104length(word) ≤ length(sentence)OutputWe have to return an integer which is the number of occurrences of the single word 'word' in the string 'sentence'.

Create a simple function named wordCount that takes a sentence (String) separated with space and count the words in the sentence. The function will return the number of words in the given sentence.Use the skeleton file, to develop the function.FUNCTION wordCount(str IN VARCHAR2)Function name :   wordCountparameter  :  str datatype VARCHAR2Function return type : NumberNote:Do not change the function nameDo not change the argument count and orderDo not change the output text.You can query the table records using select statementDelimiter / is mandatory. If delimiter is missed, then while executing nothing will be displayedWhile executing, if you get WARNING: FUNCTION CREATED WITH COMPILATION ERRORS, then use SHOW ERRORS to display the errors in the function.Instructions:1. Create the function successfully2. Once the function is created, check the functionality of the function using appropriate select call3. DO NOT submit the select statement. Submit only the CREATE FUNCTION query.Sample Input and Output:If we execute the function with "HELLO WORLD" it should return 2.SubmitSaveExecutePrevious Submission

There is a collection of input strings and a collection of query strings. For each query string, determine how many times it occurs in the list of input strings. Return an array of the results.ExampleThere are instances of '', of '' and of ''. For each query, add an element to the return array, .Function DescriptionComplete the function matchingStrings in the editor below. The function must return an array of integers representing the frequency of occurrence of each query string in stringList.matchingStrings has the following parameters:string stringList[n] - an array of strings to searchstring queries[q] - an array of query stringsReturnsint[q]: an array of results for each queryInput FormatThe first line contains and integer , the size of .Each of the next lines contains a string .The next line contains , the size of .Each of the next lines contains a string .Constraints .Contest ends in 2 hoursSubmissions: 86Max Score: 10Difficulty: MediumRate This Challenge: More Python 31#!/bin/python32​3import math4import os5import random6import re7import sys8​9#10# Complete the 'matchingStrings' function below.11#12# The function is expected to return an INTEGER_ARRAY.13# The function accepts following parameters:14# 1.

Define the function count_substring(string, substring) that finds how many times the substring appears in the given string.Example:string = "Python is a powerful language. I want to learn Python"substring = "Python"Expected Output:2

Select the correct implementation of a piece of code that accepts a sentence as input and prints the number of words in it. A sentence is just a sequence of words with a space between consecutive words. You can assume that the sentence will not have any other punctuation marks. You can also assume that the input string will have at least one word.1sentence = input()2space = ' ' # there is a single space between the quotes3num_words = sentence.count(space)4print(num_words)1sentence = input()2space = ' ' # there is a single space between the quotes3num_words = sentence.count(space) + 14print(num_words)1sentence = int(input())2space = ' ' # there is a single space between the quotes3num_words = sentence.count(space)4print(num_words)1sentence = input()2num_words = len(sentence)3print(num_words)
