Given two strings needle and haystack, return the index of the first occurrence of needle in haystack, or -1 if needle is not part of haystack. Example 1: Input: haystack="sadbutsad", needle = "sad" Output: 0 Explanation: "sad" occurs at index 0 and 6. The first occurrence is at index 0, so we return 0. Example 2: Input: haystack="leetcode", needle="leeto" Output: -1 Explanation: "leeto" did not occur in "leetcode", so we return -1. Write C# code

The countSubstring function will take two strings as parameters and will return an integer that is the count of how many times the substring (the second parameter) appears in the first string without overlapping with itself. This method will be case insensitive. For example: countSubstring(“catwoman loves cats”, “cat”) would return 2 countSubstring(“aaa nice”, “aa”) would return 1 because “aa” only appears once without overlapping itself. public static int countSubstring(String s, String x) { if (s.length() == 0 || x.length() == 0) return 1; if (s.length() == 1 || x.length() == 1){ if (s.substring(0,1).equals(x.substring(0,1))){ s.replaceFirst((x), " "); return 1 + countSubstring(s.substring(1), x); } else { return 0 + countSubstring(s.substring(1), x); } } return countSubstring(s.substring(0,1), x) + countSubstring(s.substring(1), x); } public class Main { public static void main(String[] args) { System.out.println(Recursion.countSubstring("catwoman loves cats","cat"));…
Actual timings. Instrument FrequencyCounter to use Stopwatch and StdDrawto make a plot where the x-axis is the number of calls on get() or put() and the y-axisis the total running time, with a point plotted of the cumulative time after each call.Run your program for Tale of Two Cities using SequentialSearchST and again usingBinarySearchST and discuss the results. Note : Sharp jumps in the curve may be explained by caching, which is beyond the scope of this question.
Suppose you are a computer salesman and your income depend on the total sales and commissions earned for the computers that you sell. Commission rates vary depending on how many units you sold (see chart below). Your income equals to the total sales plus the commission where the commission equals to total sales times the commission rate. That is, commission = total sales * commission rate and income = total sales + commission. Total Sales Commission rate % Less than 200 sold 8% (totalsales < 200) Greater or equal to 200 sold 10% (totalsales >=200 & totalsales <400) Greater than to 400 sold 12% (if (totalsales >= 400) Use Multiway if, else if (use as many you need) and else correctly Review slides 3-CH-2 Slide 4 and 8 Write the code correctly as show in the chapter slides.

Question 1: As you are a student of university now, you need to ensure your assignments are plagiarism-free. To do this, you decide to design a simple plagiarism checker. Your checker will take 2 strings as input. Then it will compare the 2 strings and check how many words they have in common. Then, print the percentage in common, by calculating: (No. of words in common / (No of words in string 1+ No of words in string 2)) * 100. If the calculated plagiarism is greater than or equal to 30%, print "Plagiarism detected." Otherwise, print "Good job!". Note: you need to compare "words" not individual characters. You can consider that all characters in both inputs will be in only lowercase or uppercase. ========= ======== Sample Input 1: my dog's name is bob bob is my dog's name Sample Output 1: Common percentage: 50% Plagiarism detected. Explanation 1: Length of string1= 5, Length of string2= 5, number of common words= 5. Hence, common percentage= (5/(5+5))*100 = 50 %3D Sample Input 2: my…
