- Write and test a function to meet this specification.drawFace (center, size, win) center is a Point, size is an int, andwin is a GraphWin. Draws a simple face of the given size in win.Your function can draw a simple smiley (or grim) face. Demonstrate thefunction by writing a program that draws several faces of varying size in asingle window.Implement the FindText() function, which has two strings as parameters. The first parameter is the text to be found in the user provided sample text, and the second parameter is the user provided sample text. The function returns the number of instances a word or phrase is found in the string. In the PrintMenu() function, prompt the user for a word or phrase to be found and then call FindText() in the PrintMenu() function. Before the prompt, call cin.ignore() to allow the user to input a new string.Ex: Enter a word or phrase to be found: more "more" instances: 5Write an application that reads a five-letter word from the user and produces every possible three-letter string that can be derived from the letters of that word. For example, the three-letter words produced from the word “bathe” include “ate,” “bat,” “bet,” “tab,” “hat,” “the” and “tea.”

Letters are case sensitive, for example, "Aa" is not considered a palindrome here. Constraints: 1 <= s.length <= 2000 s consists of lowercase and/or uppercase English letters only. Function definition for Java: public int longestPalindrome(String s) { } Function definition for Python: def longestPalindrome(self, s): #Your code here Announced Test Cases: Example 1: Input: s = "abccccdd" Output: 7 Explanation: One longest palindrome that can be built is "dccaccd", whose length is 7. Example 2: Input: s = "speediskey"Output: 5Explanation: The longest palindrome that can be built is "seees", whose length is 5.
- Write a JavaScript function that accepts a number from a user as input and checks if the number is prime, then print True if the number is not a prime, print False.

- When testing this java program I get a java.lang.NullPointerException for 3 sections of the function, specifically String remove, String reverse and String filterLettersIn JAVA A function foo takes three integers as input arguments, i.e., foo(int a, int b, int c). The three inputs represent the three sides of a triangle in centimeter. The function is expected to return the type of a triangle: “equilateral”, “isosceles”, or “scalene”. Assume the domains of the three variables are 1 ≤ a ≤ 100, 50 ≤ b ≤ 150 and 100 ≤ c ≤ 200, respectively. A test case is in a tuple format <a, b, c, expected_output> with test inputs and the expected output. S1 is a set of test cases for the “Boundary Value Analysis” approach. S1 = S2 is a set of test cases for the “Robustness testing” approach. S2 – S1 = S3 is a set of tests cases for the “Robust Worst-Case testing” approach. Are there any types of triangles that S3 cannot reveal? If yes, what are they? If no, why?Write a program that does two string functions: capitalize the first word of a phrase, and reverse the letters of words in odd positions within the phrase. For this program it is acceptable to let punctuation be part of the word. Write a capitalizeWords() and a reverseOddWords() method and call them in a test program. Make certain to properly handle empty phrases, phrases with one and two words, and phrases with greater than two words. For example, if the original phrase were: Learning Java is fun! Java is powerful and easy to use The capitalized version would be: Learning Java Is Fun! Java Is Powerful And Easy To Use And with reversed odd words would be: gninraeL Java sI Fun! avaJ Is lufrewoP And ysaE To esU
