313. Check if two Strings are equal without using built-in function
Objective- Given two strings, find out if they are equal or not without using any built-in function (without using equals() function in java).
Example:
String x='tutorial' and String y='tutorial' are equal - true String x='tutorial' and String y='tutorial ' are equal - false String x='tutorial' and String y=' ' are equal – false
Approach:
- If any of the string is null, return false.
- If lengths of both strings are not matching, return false.
- Check if all the characters of both strings are matching, if not return false.
- If all the steps above got executed without returning false then return true.
Output:
String x='tutorial' and String y='tutorial' are equal?? -true String x='tutorial' and String y='tutorial ' are equal?? -false String x='tutorial' and String y=' ' are equal?? -false
