Output a half pyramid of stars with a height determined by the user. If the user enters a number less than one, exit. Write the code in java and use the test case example as reference ### Test Case 7**Prompt:**- Enter a height: - User input: `30`**Output:**- A right-aligned triangle of asterisks (`*`) with 30 rows. - Each row contains an increasing number of asterisks starting from 1 up to 30, with the first line having one asterisk and the last line having 30 asterisks.**Structure:**- Row 1: `*`- Row 2: `**`- Row 3: `***`- ...- Row 30: `******************************`### Test Case 8**Prompt:**- Enter a height: - User input: `-32432`**Output:**- Error Message: "Height must be at least one."### ExplanationThe diagrams demonstrate how the user inputs a height to generate a triangle made of asterisks. The input should be a positive integer, as negative values result in an error message. ### Pattern Printing: Test Cases and Results#### Test Case 1- **Input:** - Prompt: "Enter a height" - User enters: `5`- **Output:** ``` * ** *** **** ***** ```#### Test Case 2- **Input:** - Prompt: "Enter a height" - User enters: `1`- **Output:** ``` * ```#### Test Case 3- **Input:** - Prompt: "Enter a height" - User enters: `10`- **Output:** ``` * ** *** **** ***** ****** ******* ******** ********* ********** ```### ExplanationThe above test cases demonstrate a simple algorithm that prints a right-angled triangle pattern of asterisks. The user is prompted to enter a height, and then a triangle with that many rows is printed, where each row contains a number of asterisks equal to the row number. - In **Test Case 1**, a height of 5 results in a triangle with 5 rows.- In **Test Case 2**, a height of 1 results in a single asterisk.- In **Test Case 3**, a height of 10 results in a larger triangle with 10 rows.

Java Code Only: The chef gives you an A sequence of N's length. Let X mean MEX for A sequence. The cook is interested in calculating the correct values k, so that, if the whole part of Ai A is replaced by max (Ai – k, 0), the MEX sequence remains X.. Find calculations for such values. If there are such endless numbers, print - 1 instead. As a friendly reminder, MEX sequence is the smallest non-negative number non-sequential. Input 1 4 1235 Output

n this lab, you complete a prewritten Python program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is make of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering.
Understanding ifStatements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs.

Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge). A variable for the number of characters initialized to 8 (numChars). A variable for the color of the characters initialized to "gold" (color). A variable for the…
Hey all, Need some help on best way to go about this question. All coding is done in Java. I am using the IntelliJ Idea, as the base for the code if it helps. Question is as follows: A car’s miles-per-gallon (MPG) can be calculated with the following formula: MPG = Miles driven / Gallons of gas used Write a java program that prompts the user for the number of miles driven and the gallons of gas used. It should calculate the car’s miles-per-gallon and display the result on the screen.
