Problem statementSend feedbackYou are given two strings 'STR1' and 'STR2'. You need to tell whether the strings are meta strings or not.Meta strings are strings that can be made equal by swapping exactly one pair of distinct characters in one of the strings.Note:Equal strings are not considered as meta strings.
Question
Problem statementSend feedbackYou are given two strings 'STR1' and 'STR2'. You need to tell whether the strings are meta strings or not.Meta strings are strings that can be made equal by swapping exactly one pair of distinct characters in one of the strings.Note:Equal strings are not considered as meta strings.
Solution
To determine if two strings are meta strings, follow these steps:
-
Check if both strings are of the same length. If not, they cannot be meta strings.
-
If they are of the same length, iterate through both strings simultaneously. Keep track of the characters that differ in both strings.
-
If there are more than two characters that differ, the strings cannot be meta strings.
-
If there are exactly two characters that differ, check if swapping these characters in one of the strings makes the two strings equal. If yes, they are meta strings. If not, they are not meta strings.
-
If there is only one character that differs, the strings cannot be meta strings.
-
If all characters are the same, the strings are not considered as meta strings, as per the problem statement.
This is a simple algorithm to check if two strings are meta strings. It can be implemented in any programming language.

Problem StatementBob loves playing a string-matching game where he tries to match two strings based on a specific pattern. In this game, players input two strings, and the game determines whether they match according to a set of rules. Here are the rules of the game:A '*' in the first string represents zero or more characters.A '?' in the first string represents exactly one character.Any other character in the first string must match the corresponding character in the second string.Bob has requested your assistance in completing the game mentioned above.Input format :The first line of input consists of a string str1 containing the characters along with the symbols - ? and *.The second line consists of the string str2, without any symbols.Output format :The first line displays the "Second string: " followed by str2 as string, representing the second input string.The second line displays the following format:"The strings match" if the first string matches the second according to the pattern rules."The strings do not match" if the first string does not match the second according to the pattern rules.Refer to the sample output for the formatting specifications.Code constraints :In the given scenario, the test cases fall under the following constraints:2 ≤ length of the string (str1, str2) ≤ 15Sample test cases :Input 1 :i?mneoiamneoOutput 1 :Second string: iamneoThe strings matchInput 2 :i?miaamOutput 2 :Second string: iaamThe strings do not matchInput 3 :i*mn?oiaamneoOutput 3 :Second string: iaamneoThe strings matchInput 4 :a?b?c?d?e?f?ghaxbxcydzefffghOutput 4 :Second string: axbxcydzefffghThe strings matchInput 5 :a*cacOutput 5 :Second string: acThe strings matchNote :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.

Raksha is developing a program to compare the lengths and content of two strings. She wants to write a program that takes two strings without any spaces as input and determines if they have the same length using the strlen function and content using the strcmp function. The program should print the length of each string and whether the strings are the same or not.Input format :The first line of input consists of a string, str1 representing the first string.The second line of input consists of a string, str2 representing the second string.Output format :The first line displays "Length of Str1 is " followed by an integer representing the length of the first string.The second line displays "Length of Str2 is " followed by an integer representing the length of the second string.The third line of output displays "The strings are the same" if they have the same content. Otherwise, it displays "The strings are not the same".
