Please read the instructions carefully and keep in mind of the bolded phrases. You are NOT ALLOWED to use HashSet Create a project in NetBeans and name the project Hw06. The class will contain the following static methods: reverseS – A method that displays a string reversely on the console using the following signature: publicstaticvoidreverseS(Strings) printSub1 – print all substrings of a string (duplicated substrings are allowed, but loops are not allowed). The method signature: public static void printSub1(String s) printSub2 – print all substrings of a string (duplicated substrings are not allowed, but loops are allowed). The method signature: public static void printSub2(String s) Note: All methods should be RECURSIVE. Any predefined classes that are based on Set are not allowed. In the main method, read a string from the user and output the reversed string and substrings to the screen: Sample Run: Please input a string: abcdThe reversed string: dcbaThe substrings…
ProblemYou are in an environment where you do not have access to a built-in, cryptographically strong pseudo-random number generator. You have obtained enough entropyto seed a pseudo-random generator, but you lack a generator.
Print a message telling a user to press the letterToQuit key numPresses times to quit. End with newline. Ex: If letterToQuit = 'q' and numPresses = 2, print:Press the q key 2 times to quit. #include <iostream>using namespace std; int main() { char letterToQuit; int numPresses; cin >> letterToQuit; cin >> numPresses; /* Your solution goes here */ return 0;}
count the most frequent letter in string permutation example : if x = icyz and j = ixpc, then there are 8 different passwords that you can choose: icyz,icyc, icpz, icpc, ixyz, ixyc, ixpz, ixpc. icpc has the most frequent letter so the output is 2 please help with c++ code (studio.h, string.h,math.h only)
Please explain this code it talks about the encryption using the Ceaser cipher void encrypt(char message[], int key){ int a; for (a = 0; (a < 50 && message[a] != '\0'); a++) // especially here message[a] = message[a] + key; cout<<"\nEncrypted string is: "<< message<<"\n"; }
PLEASE COMPLETE IN PYTHON (do not copy the answer that is already there from someone else it does not contain the spark application to answer the below part) - Thank you!!!! Write a spark application that reads in the names of two files from STDIN and outputs the number of strings they have in common to STDOUT. Each file contains 1 million strings of 32 characters, 1 per line. Note that the same value appears in both files 100 million times. Please write the spark application using the reduceByKey() transformation to count the number of occurrences of each value and filter out the values that occur less than 100 million times. Sample input:strings_1.txtstrings_2.txt Sample output:417653
<<Write in Java>> - Challenge 7 File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. - Challenge 8 Write a program that decrypts the file produced by the program in Programming Challenge 7. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another file
