Given 2 binary strings A and B of the same length, find the minimum number of operations needed to change string A to B. The operations are defined as follows:AND Operation:Choose a pair of indices i and j such that i != j and perform the following sequence of operations.result = Ai & AjAi = result & AiAj = result & AjOR Operation:Choose a pair of indices i and j such that i != j and perform the following sequence of operations.result = Ai | AjAi = result | AiAj = result | AjXOR Operation:Choose a pair of indices i and j such that i != j and perform the following sequence of operations.result = Ai ^ AjAi = result ^ AiAj = result ^ AjInput FormatThe first line of input contains T - the number of test cases. It's followed by 2T lines, the first line contains string A and the second line contains string B.Output FormatFor each test case, if conversion is possible, print "YES" followed by the minimum number of operations required to convert string A to string B, otherwise print "NO", separated by a new line.Constraints1 <= T <= 10001 <= len(A)==len(B) <= 103ExampleInput210101010101011OutputYES 2YES 1ExplanationTest-Case 1We can choose index-1 and index-2 of string A and perform the XOR operation. The resultant string will look like 110. After that, we can choose index-0 and index-2 of the new string A and perform the AND operation. The resultant string will look like 010.

You are given two strings, A and B. Answer, what is the smallest number of operations you need totransform A to B?Operations are:Delete one letter from one of stringsInsert one letter into one of stringsReplace one of letters from one of strings with another letterInputT - number of test casesFor each test case:String AString BBoth strings will contain only uppercase characters and they won't be longer than 2000 characters. There will be 10 test cases in data set.OutputFor each test case, one line, minimum number of operations.ExampleInput:1FOODMONEYOutput:4

You have given two strings 'A' and ‘B’ of length ‘N’ each which only consists of lowercase English letters. You have also given an integer ‘K’.Your task is to determine if it is possible to convert string ‘A’ into ‘B’ after performing two types of operations on it:1. Choose an index i (1 <= i <= N - 1) and swap A[i] and A[i+1].2. Choose an index i (1 <= i <= N - K + 1) and if A[i], A[i+1],. . . . , A[i+K-1] all are equal to some character x (x != ‘z’), then you can replace each one with the next character (x + 1) , i.e. ‘a’ is replaced by ‘b’, ‘b’ is replaced by ‘c’ and so on.Note:You are allowed to perform any operation any number of times(possibly zero) only on string 'A'.

Johnwick has a string s1s2...sn and a character c , he only loves character c so he wants to change all character of his string into c using the minimum number of operations. In one operation he can choose a number x (1≤x≤n) and for every position i, where i is not divisible by x, replace si with c. Note - You have to complete the function solve and return - One vector of size m (number of operation you needed) of element which you have taken as x in the same order. if no operation needed then just return empty vector. Input Format : First line of input will contain one integer t - number of test cases(1 <= t <= 100). The first line of each test case contains the integer n (3 ≤ n ≤ 3⋅10^4) and a lowercase Latin letter c — the length of the string s and the character the resulting string should consist of. The second line of each test case contains a string s of lowercase Latin letters — the initial string. It is guaranteed that the sum of n over all test cases does not exceed 3⋅10^4. Output Format : You will receive 1 your answer is ok otherwise -1. Sample Input : 3 4 a aaaa 4 a baaa 4 b bzyx Sample Output: 1 1 1 give java code

You are given a collection of N non-empty strings, denoted by S 1 , S 2 , … , S n . Then you are given N - 1 operations which you execute in the order they are given. The i t h operation is has the following format: ‘ a b ’ ( 1 -based indexing, without the quotes), which means that you have to make the following changes: S a = S a + S b , i.e. concatenate a t h string and b t h string and store the result in a t h string, S b = "", i.e. make the b t h string empty, after doing the previous step. You are ensured that after the i t h operation, there will be no future operation that will be accessing S b . Given these operations to join strings, print the last string that will remain at the end of this process. Input The first line contains an integer N ( 1 ≤ N ≤ 10 5 ) denoting the number of strings given. Each of the next N lines contains a string denoting the S i . All the characters in the string S i are lowercase alphabets from ‘a’ to ‘z’. The total number of characters over all the strings is at most 10 6 , i.e ∑ i = 1 N | S i | ≤ 10 6 , where | S i | denotes the length of the i t h string. After these N strings, each of the next N - 1 lines contain two integers a and b , such that a ≠ b and 1 ≤ a , b ≤ N denoting the i t h operation. Output Print the last string which remains at the end of the N - 1 operations. Warning The I/O files are large. Please use fast I/O methods. can you write a java solution, and pick the one that is the most efficient time wise

You are given two strings a𝑎 and b𝑏 of length n𝑛. Then, you are (forced against your will) to answer q𝑞 queries.For each query, you are given a range bounded by l𝑙 and r𝑟. In one operation, you can choose an integer i𝑖 (l≤i≤r𝑙≤𝑖≤𝑟) and set ai=x𝑎𝑖=𝑥 where x𝑥 is any character you desire. Output the minimum number of operations you must perform such that sorted(a[l..r])=sorted(b[l..r])sorted(a[l..r])=sorted(b[l..r]). The operations you perform on one query does not affect other queries.For an arbitrary string c𝑐, sorted(c[l..r])sorted(c[l..r]) denotes the substring consisting of characters cl,cl+1,...,cr𝑐𝑙,𝑐𝑙+1,...,𝑐𝑟 sorted in lexicographical order.InputThe first line contains t𝑡 (1≤t≤10001≤𝑡≤1000) – the number of test cases.The first line of each test case contains two integers n𝑛 and q𝑞 (1≤n,q≤2⋅1051≤𝑛,𝑞≤2⋅105) – the length of both strings and the number of queries.The following line contains a𝑎 of length n𝑛. It is guaranteed a𝑎 only contains lowercase latin letters.The following line contains b𝑏 of length n𝑛. It is guaranteed b𝑏 only contains lowercase latin letters.The following q𝑞 lines contain two integers l𝑙 and r𝑟 (1≤l≤r≤n1≤𝑙≤𝑟≤𝑛) – the range of the query.It is guaranteed the sum of n𝑛 and q𝑞 over all test cases does not exceed 2⋅1052⋅105.OutputFor each query, output an integer, the minimum number of operations you need to perform in a new line.ExampleinputCopy35 3abcdeedcba1 51 43 34 2zzdeazbe1 31 46 3uwuwuwwuwuwu2 41 31 6outputCopy01022110NoteFor the first query, sorted(a[1..5])=sorted(a[1..5])= abcde and sorted(b[1..5])=sorted(b[1..5])= abcde, so no operations are necessary.For the second query, you need to set a1=𝑎1= e. Then, sorted(a[1..4])=sorted(b[1..4])=sorted(a[1..4])=sorted(b[1..4])= bcde.
