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. Otherwise, check if string A can be converted to string B by following the given step.
- Select a prefix from string A.
- Increase the alphabetical value of all characters in the prefix by the same valid amount.
- Check if the resulting string is equal to string B.
- If yes, print "YES" and move to the next pair.
- If no, repeat the above steps with different prefixes until all possibilities are exhausted. c. If no conversion is possible, print "NO".
-
Repeat step 3 for all pairs of input strings.
-
Print the output for each pair of strings.
Sample Input: 3 abaca cdbda godzjneaaqlmcmmo
Sample Output: YES NO
Explanation for the first pair of strings: The string "abaca" can be converted to "bcbda" in one move by increasing the alphabetical value of the prefix "aba" by 1. It can then be converted to "cdbda" in the next move by increasing the alphabetical value of the prefix "bcb" by 1. Since the conversion is possible, the output is "YES".
Solution 2
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. Otherwise, iterate through each character in string A and compare it with the corresponding character in string B. c. If the characters are not equal, check if the alphabetical value of the character in string A can be increased to match the alphabetical value of the character in string B. d. If it is possible to increase the alphabetical value, continue checking the remaining characters. e. If at any point it is not possible to increase the alphabetical value to match the corresponding character in string B, print "NO" and move to the next pair. f. If all characters can be converted to match string B, print "YES".
-
Repeat step 3 for each pair of input strings.
-
Print the output for each pair of input strings.
The output 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'.

Given two strings s and t, determine if they are isomorphic.Two strings s and t are isomorphic if the characters in s can be replaced to get t.All occurrences of a character must be replaced with another character while preserving the order of characters. No two characters may map to the same character, but a character may map to itself. Example 1:Input: s = "egg", t = "add"Output: trueExample 2:Input: s = "foo", t = "bar"Output: falseExample 3:Input: s = "paper", t = "title"Output: true Constraints:1 <= s.length <= 5 * 104t.length == s.lengths and t consist of any valid ascii character.
