java:
Run length coding is a method to represent a string in a more compact manner. Each character that occurs more than 2 times in a row is represented by the character and a number following it. Two examples are:
"abba" → "abba""abcccbbbba" → "abc3b4a"Write a function that calculates how many characters the encoded string is shorter than the original.
program to demonstrates how to perform (1. finding a substring in a string, 2. determining the length of a string, and 3. determining the position of a character in a string.) operations. A String object is instantiated to the string “Hello world”. We then break the string into its two constituent pieces: the first word and the second word.
Computer science. Correct answer will be upvoted else downvoted.
You are given a string s comprising of the characters 0, 1, and ?.
We should call a string unsteady in the event that it comprises of the characters 0 and 1 and any two contiguous characters are unique (I. e. it has the structure 010101... or then again 101010...).
How about we call a string delightful in the event that it comprises of the characters 0, 1, and ?, and you can supplant the characters ? to 0 or 1 (for each character, the decision is free), so the string becomes shaky.
For instance, the strings 0??10, 0, and ??? are wonderful, and the strings 00 and ?1??1 are not.
Ascertain the number of delightful adjacent substrings of the string s.
Input
The main line contains a solitary integer t (1≤t≤104) — number of experiments.
The solitary line of each experiment contains the string s (1≤|s|≤2⋅105) comprising of characters 0, 1, and ?.
It is ensured that the amount of the string lengths…

Create the function binary_to_ascii_string() that accepts a list of binaries, binary_values, and returns them as a string. As an example, the list [‘01000001’, ‘01101100’, ‘01100101’, ‘01111000’] will return the string ‘Alex’ and the list [‘01100100’, ‘01110101, ‘01100100’, 01110101] will return the string ‘dudu’.arrow_forwardWrite a C++ or Java program that uses bit strings to find A ∪ B, A ∩ B, and A – B given subsets A and B of a universal set with 10 elements {0, 1, 2, 3, 4, 5, 6, 7, 8,9}. You have to use bit string Print to the screen set A, set B ( be sure to print out the name of the sets), as well as the set operation results(be sure to print out the name of the operations). The program requires that elements of subsets A and B are from user input. You can make the assumption that user input numbers are within the domain of the set {0, 1, 2, ..., 9} and there is no improper input.Additional requirements and reminders:• The use of STL, templates, and operator overloading is not permitted in any form.• Remember: You must use a bit string when representing a set. You may not use an array ofBoolean variables.• The elements of subset A and subset B must from user input. You may not hardcode the two subsets in your program.Hint:(1) It is a bit easier to program if we construct the bit string of a set…arrow_forward

- (Java) Write a program that uses String method regionMatches to compare two strings input by the user. The program should prompt the user to enter two strings, the starting index in the first string, the starting index in the second string, and the number of characters to be compared. The program should print whether or not the strings are equal. (Ignore the case of the characters during comparison.)

Each of n users spends some time on a social media site. For each i = 1, . . . , n, user i enters the site at time ai and leaves at time bi ≥ ai. You are interested in the question: how many distinct pairs of users are ever on the site at the same time? (Here, the pair (i, j) is the same as the pair (j, i)).Example: Suppose there are 5 users with the following entering and leaving times: Then, the number of distinct pairs of users who are on the site at the same time is five: these pairs are (1, 2), (1, 3), (2, 3), (4, 6), (5, 6).
