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.

We can calculate BMI from the weight of the person (in pounds) and the height (in inches) of the person.The formula for calculating BMI is:BMI = (weightInPounds * 703) divided by (heightInInches squared)In this problem, you will develop a Java program as a BMI calculator, that reads the user’s weight in pounds and height in inches, then calculates and displays the user’s body mass index BMI. Also, display the following information {from the US Department of Health} so the user can evaluate his/her BMI:BMI values:Underweight: less than 18.5Normal: between 18.5 and 24.9Overweight: between 25 and 29.9Obese: 30 or greaterarrow_forwardAnalyze the following code. int x = 13B while (0 < x) && (x < 100) System.out .printin(x++); The numbers 2 to 100 are displayed.

Suppose that the loan amount is L, r is the interest rate per year, m is the number of payments in a year, and the loan is for t years. Suppose that i = (r / m) and r is in decimal. Then the periodic payment is (first image which R=....): You can also calculate the unpaid loan balance after making certain payments. For example, the unpaid balance after making k payments is (second image which L'=....) : where R is the periodic payment. (Note that if the payments are monthly, then m = 12.) Instructions Write a program that prompts the user to input the values of L, r, m, t, and k. The program then outputs the appropriate values. Your program must contain at least two functions, with appropriate parameters, to calculate the periodic payments and the unpaid balance after certain payments. Make the program menu driven and use a loop so that the…arrow_forward3.

- The objective of this program is to demonstrate your proficiency with the if-elif-else construct. Your program will consist of a simple guessing game. Using the random module, generate an integer between 1 and 10. This will be the secret. You will then ask the user for a guess between 1 and 10. . If the guess is greater than the secret respond, "Too high". • If the guess is less than the secret respond, "Too low". . If both numbers are equal respond, "Success!". Remember to test your program to ensure that all of the comparisons work. Please note that a loop is not required. The images below shows the program being run multiple times to display the three different possible output messages. Your display should look like this. User input is highlighted in green. Please enter your guess: 10 Too high! Please enter your guess: 5 Too low! Please enter your guess: 1 Success!arrow_forwardThe Game of Nim: The game of Nim starts with a random number of stones between 15 and 30. Two players alternate turns and on each turn may take either 1, 2, or 3 stones from the pile. The player forced to take the last stone loses. The computer player will make random choices during their turn. Your program must check to make sure that neither the computer nor the human player attempts to take 3 if there are only 1 or 2 stones left. The computer should only take 1 or 2 stones when 3 are left, and only 1 stone when 2 stones are left. Make sure you are using functions, importing random, and making it at around grade 10 coding levels, haha!arrow_forwardFix any errors that you find. Use in-line comments to explain how and why you fixed the bugs. Test your program. If you found and fixed all the errors, your code should function as specified: The code should allow users to enter basic, one operator arithmetic expressions using integers or doubles. Then, it should calculate the result of the expression and output the results. For example, if the user inputs “2 + 2,” the calculator should output “2 + 2 = 4.” The operations the program should perform are addition (+), subtraction (-), multiplication (*), and division (/). The user should be asked whether they wish to continue after evaluating each expression. If the user types “Y” or “y,” the program should ask for a new arithmetic expression. If the user types “N” or “n,” the program should terminate with the message: “Program Finished.”arrow_forward
