Write a JAVA program for HTML is the language of web pages. Items start and end with tags. A table starts with and ends with . In a table, a row starts with and ends with . In a row, a column starts with and ends with . Given two integers for rows and columns, generate an appropriately sized html table. Place the character c in each table cell. If the input is 2 3, the output is: c c c c c c

Q12,. A phrase is a palindrome if, after converting all uppercase letters into lowercase letters and removing all non-alphanumeric characters, it reads the same forward and backward. Alphanumeric characters include letters and numbers. Given a string s, return true if it is a palindrome, or false otherwise.   Example 1: Input: s = "A man, a plan, a canal: Panama" Output: true Explanation: "amanaplanacanalpanama" is a palindrome. Example 2: Input: s = "race a car" Output: false Explanation: "raceacar" is not a palindrome..

A grid needs a system for numbering the tiles in order to allow random-access lookup.For instance, the rows and columns of a square grid provide a natural numbering for the tiles. Create plans for hexagonal and triangular grids. Create a rule for identifying the neighbourhood (i.e., nearby tiles) of a certain tile in the grid using the numbering scheme. For instance, the neighbourhood of tile I j in a four-connected square grid with indices of I for rows and j for columns may be described as neighbourhood(i, j) = I 1, j, I j 1.

Write a program that lists all Fibonacci numbers that are less than or equal to the number k (k≥2) entered by the user. Definition:The Fibonacci sequence is a sequence of numbers in which each additional term is the sum of the previous two. It is based on the fact that each member of the sequence is formed by the sum of the previous two members, the sequence starting with the numbers 1 and 1. (Example 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233 , 377, 610, 987   write program in c language

Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segment

Write a program in C++ that can perform encryption and decryption using an arbitrary substitution cipher. In this case, the encrpyion array is a random shuffling of the letters in the alphabet. Your program should generate a random encryption array, its corresponding decryption array, and use these to encode and decode the message.

Write a program that reads a sequence of input values and displays a bar chart of the values, using asterisks, like this: ********************** **************************************** **************************** ************************** ************** You may assume that all values are positive. You will keep reading input until the letter Q is entered. In order to solve this problem, you need to first figure out the maximum entered value. That value’s bar should be drawn with 40 asterisks. Shorter bars should use proportionally fewer asterisks. Make sure that you use functions in your solution, including a main function. Define def readInts() function to read integers until user enters q. and returns a list of entered integers Define def printStars(values) function that prints the bar chart using the list of values

IN JAVA Write a function that takes in user input as a string. For all characters which are numeric, double its value and, if it is two digits, then replace it with the sum of its digits (e.g., 6 → 12 → 3 whereas 3 → 6). For all characters which are in uppercase, replace it with lowercase. For all characters which are in lowercase, replace it with uppercase (e.g., m → M and N → n).  The program should keep asking the user to enter strings until they either enter ‘q’ or ‘Q’.

Write a program that computes and prints the mean and standard deiviation of a list of integers x1 through xn. Assume there will be no more than 50 input values. Compute both the mean and standard deviation as floating point values.

Consider numbers from 0 to 100. If the number being searched for is 99, then write each value of variables passed through find() that would occur while searching for the number. The first is (51,100). O (75,100) (88,100) (94,100) (97,100) (99,100) O (75,100) (88,100) (94,100) (97,100) (99,99) O (76,100) (89,100) (95,100) (99,100) (76,100) (89,100) (95,100) (98,100)
