- Create a string from two given strings by concatenating common characters of the given strings. Sample Input harry, hermione dean, tom Sample Output hrrhr Nothing in common. Again, you have lost your USIS password!! You went to the registrar office and requested for a new password. This time, you need to follow some rules to set your password. Otherwise, they won't change it. The rules are At least one lowercase letter At least one uppercase letter At least one digit (0-9) At least one special character (_ , $ , #, @) Your task is to find whether a given password follows all those rules. If it breaks any rule, you have to print Lowercase Missing, Uppercase Missing, Digit Missing or Special Missing respective to the missing case. For more than one rule break, print all the rules that were broken (order doesn't matter). If the password is ok, print OK. Sample Input ohMyBR@CU ohmybracu OhMyBR@CU20 Sample Output Digit missing Uppercase character missing,…Write a program that reads a string and checks the longest substring starting with "a" and ending with "z" included in it. Note that, the substring cannot contain another a or another z in it. For example: Ifs="bcd bbccdd badefgze tabdz", the longest substring is: 6Write a program that gets a string from the user and reports whether or not there are repeated characters in it
- You have to construct a string “cmpmpcmpm” from a blank string. There are two ways to construct a string.1. Operation 1: You can add any character at the end of the string. It will cost you 5 points.2. Operation 2: You can copy any substring of string at the end of the string. It will cost you 6 points.The operations that you will choose to construct the string with minimum cost are:Palindromes - “A palindrome” is a string that reads the same from both directions. For example: the word "mom" is a palindrome. Also, the string "Murder for a jar of red rum" is a palindrome. - So, you need to implement a Boolean function that takes as input a string and its return is true (1) in case the string is a palindrome and false (0) otherwise. - There are many ways to detect if a phrase is a palindrome. The method that you will implement in this task is by using two stacks. This works as follows. Push the left half of the characters to one stack (from left to right) and push the second half of the characters (from right to left) to another stack. Pop from both stacks and return false if at any time the two popped characters are different. Otherwise, you return true after comparing all the elements. Phrases of odd length have to be treated by skipping the middle element like the word "mom", your halves are "m" and "m". - Hint: (without using STL)Write a program that gets a string from the user and maps the capital letters into small letters, and maps the small letters into capital letters. Namely, 'A' should be changed to 'a'; 'B' should be changed to 'b'; ... 'Z' should be changed to 'z'. Similarly, 'a' should be changed to 'A'; 'b' should be changed to 'B'; etc... Your program should also change the digits into next odd number. Namely, '0' should be changed to '1'; '1' should be leaved as '1'; '2' should be changed to '3'; ... '9' should be leaved as '9'. Your program should print the final form of the altered string. Example: If the user enters: My salary is 1000 TL. The output should be: mY SALARY IS 1111 tl.
- City and State. Extract the city name and state from strings like “Utica, NY” and “Los Angeles, CA”. Assume the state is always the last two characters in the string, the city name has at least one character, there is a comma following the city name, and a single space after the comma. Use the split method to separate the city name from the state (Notice the city name will still have a comma at the end). The following attachement is a sample execution:public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current stringWrite a program which reads string and rewrite it in alphabetical order. For example, the word STRING should be written as GINRST.
- Write a regular expression that defines strings that have an even (but nonzero) number of "a" characters followed by an odd number of "b" characters. For example, aab, aabbb, aaaab, and aaaabbb should all match the regular expression.You have to construct a string “cmpmpcmpm” from a blank string. There are two ways to construct a string. 1. Operation 1: You can add any character at the end of the string. It will cost you 5 points. 2. Operation 2: You can copy any substring of string at the end of the string. It will cost you 6 points. The operations that you will choose to construct the string with minimum cost are: Options Apply operation 1 five times and operation 2 four times Apply operation 1 four times and operation 2 three times Apply operation 1 three times and operation 2 two times Apply operation 1 five times and operation 2 one timeDescriptionA 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.
