Solution 1
To determine if two given strings A and B are compatible, we need to check if string A can be converted to string B by following the given step any number of times.
-
Read the value of N.
-
Read N pairs of strings, each in a separate line.
-
For each pair of input strings: a. Check if string A is equal to string B. If yes, print "YES" and move to the next pair. b. Iterate through each character in string A and string B simultaneously. c. If the characters at the current position are not equal, check if the character in string A is alphabetically smaller than the character in string B. d. If the character in string A is smaller, it is not possible to convert string A to string B. Print "NO" and move to the next pair. e. If the character in string A is greater, calculate the difference in alphabetical values between the characters. f. Iterate through the remaining characters in string A and check if their alphabetical values can be increased by the same valid amount. g. If all characters in string A can be increased by the same valid amount, print "YES". Otherwise, print "NO".
-
Repeat step 3 for each pair of input strings.
The output format should be "YES" if string A can be converted to string B, and "NO" otherwise.

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'.
