Maybe one day the Java strings will come with the reverse method built in, just like the string data types of all sensible…
- Q1__;. 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..Write a code that determines if a string is a palindrome (can be read forward and backward with the same meaning); e.g. "civic", “elle", “madam" 66 22DescriptionA researcher is analyzing DNA. A DNA can be represented as a string composed of the characters A, G, C, or T.One day, researchers found a strange DNA, which is Smooth Repeated DNA. The DNA is represented by a string that has infinite length. The string has a repeating pattern, i.e. the DNA string 0 is repeated an infinite number of times. For example, if0 = "????", then = "???????????? . . . ".According to researchers, a DNA is said to be special if it contains substrings . Determine whetheris a substring of . Squad FormatA line containing the two strings 0 and . Output FormatA line that determines whether it is a substring of . Issue “YES” ifis a substring of . Output “NO” otherwise.

- Write a program that prompts the user to enter a string anddisplaysthe string in reverse order. Enter a string: ABCD ↵EnterThe reversed string is DCBADescription Write a Java program that compares two Strings. You have to declare a String text1 and assign it the value "programming" and then declare another String text2 and assign it the value "development". Your program should do the following: If the two Strings are exactly the same print to the screen "Exactly the same: True" otherwise print "Exactly the same: False". You may use boolean variables. If and only if the first comparison was false, a comparison should be done that ignores case sensitivity. If they are the same while ignoring the case print to the screen "Similar: True" otherwise print "Similar: False". Sample Input These sentences are the same. These sentences are the same. Sample Output Exactly the same: True Sample Input This sentence has Upper case and Lower case letters. This sentence has upper case and lower case letters. Sample Output Exactly the same: False Similar: True Sample Input Well something is wrong here Obviously they will get a false output Sample…In Programming When you work with text, sometimes you need to determine if a given string starts with or ends with certain characters. You can use two string methods to solve this problem: .startswith() and .endswith()?
- Target The aim of this work is to use control structures and loops. Read carefully the problem and understand what needs to be done. Read your description is given and when you understand how it works, then start designing its solution and its implementation on the computer applying the syntax and semantics of the language Java programming. Write a LongestDupSubstring.java program that accepts a string as input and compute and print the longest sub-string displayed in two times without overlap (see 5th example for overlap). If there are more from one of such sub-strings, the program displays the first one it finds as well the number of characters in the substring. If there is no substring that appears 2 times, then the program will not print anything. Execution examples (the user's input is red and the longer in length 2 substrings) 1 Example Give a string: again and again Longest substring: again Longest substring size: 5 2 Example Give a string: seven saints and seven dinners Longest…Pig LatinWrite a program that accepts a sentence as input and converts each word to “Pig Latin.” Inone version, to convert a word to Pig Latin, you remove the first letter and place that letterat the end of the word. Then, you append the string “ay” to the word. Here is an example:English: I SLEPT MOST OF THE NIGHTPig Latin: IAY LEPTSAY OSTMAY FOAY HETAY IGHTNAY in pythoncapCount.py make a program called capCount.py that has a function that takes in a string and prints the number of capital letters in the first line, then prints the sum of their indices in the second line. The string "hEllo, World" would should look like this: 28
