You are given two strings s and t. String t is generated by randomly shuffling strings and then adding one more letter at a random position. Return the letter that was added to t. Examples findThe Difference("", "e") find The Difference ("abcd", "abcde") find The Difference ("rt", "rst") → "5" find The Difference ("gjklmn", "ghjklmn"") → "h" findTheDifference ("ae", "aea") - "a"

Correct answer will be upvoted else Multiple Downvoted. Computer science. You are given a string s, consisting of brackets of two types: '(', ')', '[' and ']'. A string is called a regular bracket sequence (RBS) if it's of one of the following type empty strin '(' + RBS + ')' '[' + RBS + ']' RBS + RBS where plus is a concatenation of two strings In one move you can choose a non-empty subsequence of the string s (not necessarily consecutive) that is an RBS, remove it from the string and concatenate the remaining parts without changing the order What is the maximum number of moves you can perfor Input The first line contains a single integer t (1≤t≤1000) — the number of testcases Each of the next t lines contains a non-empty string, consisting only of characters '(', ')', '[' and ']'. The total length of the strings over all testcases doesn't exceed 2⋅10 Output For each testcase print a single integer — the maximum number of moves you can perform on a given string…

Correct answer will be upvoted else downvoted. Computer science. section grouping is a string containing just characters "(" and ")". A standard section succession is a section grouping that can be changed into a right number juggling articulation by embedding characters "1" and "+" between the first characters of the arrangement. For instance, section successions "()()" and "(())" are normal (the subsequent articulations are: "(1)+(1)" and "((1+1)+1)"), and ")(", "(" and ")" are not. You need to find a string b that comprises of n characters to such an extent that: b is a standard section grouping; in the event that for some I and j (1≤i,j≤n) ai=aj, bi=bj. As such, you need to supplant all events of 'A' with a similar kind of section, then, at that point, all events of 'B' with a similar sort of section and all events of 'C' with a similar sort of section. Your undertaking is to decide whether such a string b exists. Input The primary line contains a solitary…

java program Write code that accomplishes the following tasks. Consider two bags that can hold strings. One bag is named letters and contain seeral one-letter strings. The other bag is empty and is namedvowels. One at a time removed a string from letters. If the string contain a vowel place it into bag vowels, otherwise, discard the string. After you have checked all of the strings in letters, report the number of vowels and the number of times each voewl appears in the bag.
IN JAVA Alice and Bob are playing a board game with a deck of nine cards. For each digit between 1 to 9, there is one card with that digit on it. Alice and Bob each draw two cards after shuffling the cards, and see the digits on their own cards without revealing the digits to each other. Then Alice gives her two cards to Bob. Bob sees the digits on Alice’s cards and lays all the four cards on the table in increasing order by the digits. Cards are laid facing down. Bob tells Alice the positions of her two cards. The goal of Alice is to guess the digits on Bob’s two cards. Can Alice uniquely determine these two digits and guess them correctly? Input The input has two integers p,q (1≤p<q≤9) on the first line, giving the digits on Alice’s cards. The next line has a string containing two ‘A’s and two ‘B’s, giving the positions of Alice’s and Bob’s cards on the table. It is guaranteed that Bob correctly sorts the cards and gives the correct positions of Alice’s cards. Output If Alice can…

A string b is an aftereffect of a string an if b can be gotten from a by cancellation of a few (conceivably, zero or all) characters. For instance, "xy" is an aftereffect of "xzyw" and "xy", yet not You are given a string a. Your errand is to reorder the characters of a so that "trygub" isn't an aftereffect of the subsequent string All in all, you should find a string b which is a stage of images of the string an and "trygub" isn't an aftereffect of b We have a genuinely superb confirmation that any string can be sorted out not to contain "trygub" as an aftereffect, however this issue explanation is too short to even think about containing it Inpu The primary line contains a solitary integer t (1≤t≤100) — the number of experiments The primary line of each experiment contains a solitary integer n (1≤n≤200) — the length of a The following line contains the string an of…
Given L = {w = {a, b}*: |w| is even}, the correct statements are: (aa U ab Uba U bb)* is a regular expression that generates L. (ab Uba)* is a regular expression that generates L. aa U ab U ba U bb is a regular expression that generates L. ab U ba is a regular expression that generates L.
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.
A spell checker in a word processing program makes suggestions when it finds a word not in the dictionary. To determine what words to suggest, it tries to find similar words. One measure of word similarity is the Levenshtein distance, which measures the number of substitutions, additions, or deletions that are required to change one word into another. For example, the words spit and spot are a distance of 1 apart; changing spit to spot requires one substitution (i for o). Likewise, spit is distance 1 from pit since the change requires one deletion (the s). The word spite is also distance 1 from spit since it requires one addition (the e). The word soot is distance 2 from spit since two substitutions would be required. a. Create a graph using words as vertices, and edges connecting words with a Levenshtein distance of 1. Use the misspelled word “moke” as the center, and try to find at least 10 connected dictionary words. How might a spell checker use this graph? b. Improve the method…
