- Do not use regular expressions in your solution for this exercise. Write a program that checks to see if an input password is valid or not. In this exercise, a valid password has the following characteristics: It contains at least eight characters. It contains at most 12 characters. It contains only alphabetic characters, digits and the underscore (‘_’) character. It does not start with a digit. It has a mix of upper-case and lower-case characters. Your class must contain the following method: public static String checkPassword(String input) This method receives a possible password as input and returns only the String“OK” if the password is valid. If the password is not valid then you can return the reason(s) for that as the return value. This is not a part of the requirements, however, and you don’t need to do that. You can simply return null for an invalid password.I need help with this problem. Please help me, because I do not understand. if 14 > 7: print("Greater than 14") x = 2 print(x * 7) else: print("Less than") print(7)I am having trouble with this: Implement the convertString method based on its specification. Here are some things that can help: the Character class has some utility methods to determine if a character is uppercase, lowercase, or a digit (numeral) the String class has a method to get the character at a specific position (called the index). Find that method and use it. make use of the convert methods you already have!convertString Specification: /** * Converts the letters and numerals in the given string * to their circled counterparts.

- Can you help me with this program?In C++ The room contains n*n cubes (in rows and columns). Each cube is white or black. You can get out of a white cube by going in one of the four directions horizontally or vertically (but you can't go beyond the scope of the room). You can get out in a black cube, but you can't get out of it. There is a mouse and a piece of cheese in the room. The mouse is in a cube (0,0) - white, and the cheese in a cube (n-1, n-1) - black. The mouse can move from cube to cube according to the rules described above. Write a program that finds all the paths that can be moved to the cheese with the mouse and if it appears, display it with ‘*’. An example diagram of the task is shown in the figure: Operating instructions: Compose a recursive function path (int i, int j), receiving as parameters the coordinates of the current position of the mouse (initially 0.0, and then run with parameters (i-1, j), (i + 1, j), ( i, j-1) or (i, j + 1)).Middle Initial Code in C language[Fish Tank] You play with a clown fish that has an initial size so. The fish can eat other fish in a tank organized in m columns and n rows. The fish at column i and row j has a positive size si,j. When your fish eats another fish, it grows by that amount. For example, if your clown fish has a size of 10 and eats a fish of size 5, it becomes of size 15. You cannot eat a fish that is bigger than your size. The game starts by eating any fish in the first (left-most) column that is not bigger than yours. After that, you advance one column at a time by moving right. You have only three allowed moves. You either stay at the same row, move one row higher or one row lower. You will always move to the right. Thus, you will make exactly m moves to advance from left to right. Your goal is to exit the fish tank from the right with the biggest possible size. The figure below shows an example with the best answer highlighted. In this case, the final fish size is 71 (10+8+7+24+22). You are required…
- use c++I am struggling with creating arrays program on eclipse. Struggling with getting the result as asked in assignment. Need help with problem a and b. Please help as soon as you can.in Swift Programming: The Big Nerd Ranch Guide (2nd Ed.) e-book: Repeat the silver challenge, but this time make sure that the formatting above matches what you print to the console. You may need to search the documentation for how to represent special characters in String literals (e.g., how do you represent a newline in a String?). You will also want to look at the documentation for the print() function to use a new parameter called terminator. This parameter defaults to printing a new line after each String logged to the console, but you will want to do something else. There are many ways to solve this challenge, but one way would be to print a String with a certain number of empty spaces (it is up to you to figure out how many!) when you print specific zip codes.
- The interest paid on a savings account is compounded daily. This means that if you start with startbal dollars in the bank, at the end of the first day you’ll have a balance ofstartbal * (1 + rate/365)dollars, where rate is the annual interest rate (0.10 if the annual rate is 10 percent). At the end of the second day, you’ll havestartbal * (1 + rate/365) * (1 + rate/365)dollars, and at the end of n days you’ll havestartbal * (1 + rate/365)ndollars. Write a program that processes a set of data records, each of which contains values for rate, startbal, and n and computes the final account balance.Please help me with this C++ code. Please show work and code output. Write a class definition that stores information for a book. I want to store the following information about this book.Questioin: Hidden Secret Problem! In this problem, you are given two names, you have to find whether one name is hidden into another. The restrictions are: You can change some uppercase letters to lower case and vice versa. You can add/remove spaces freely. You can permute the letters. And if both the names match exactly, then you can say that one name is hidden into another. Input Input starts with an integer T (≤ 100), denoting the number of test cases. Each case starts with two lines. Each line contains a name consists of upper/lower case English letters and spaces. You can assume that the length of any name is between 1 and 100(inclusive). Output For each case, print the case number and Yes if one name is hidden into another. Otherwise print No. Sample Input Output 3 Tom Marvolo Riddle I am Lord Voldemort I am not Harry Potter Hi Pretty Roar to man Harry and Voldemort Tom and Jerry and Harry Case 1: Yes Case 2: Yes Case 3: No And I want…
