Top 20 String Algorithm Questions from Coding Interviews In this article, we are going to see top 20 String based coding interview question and their solution to help programmers better prepare for interviews.
The string is one of the most important data structure and available in almost every programming language e.
Though there implement differ but the essence remains same e. The string is also available on weekly typed language e. This is why you will always find some String based coding question on programming interview.
Even in your college days, you would have solved lots of coding problems based upon String like reversing String in place, checking if String is a palindrome, checking if two strings are an anagram of each other, calculating permutations of String etc.
This article contains both easy and difficult String coding questions for your preparation. I have not posted the solution right behind the problem so that you can give it a shot before checking solution.
You can solve these String based coding question on any language of your choice e.
Remember, there are many algorithms to solve the same problem, and you should know that, mainly to handle follow-up question better. Also remember to solve same question using both recursion and iteration, as interviewer really like to ask iterative version if you come up with recursive algorithm and vice-versa.
Nevertheless, if you see your favorite question is not included in list, feel free to suggest, I will include it. You can also post question asked to you on your interview and you have not find its solution yet.
Some questions are still unsolved or solution is not yet posted on my blog. Also difficult level increases as you move questions.
Bonus points if your program is robust and handle different kinds of input e. String without duplicate, null or empty String etc. Bonus points if you also write unit tests for normal and edge cases.
You need to write a Java program to check if two given strings are anagrams of Each other. Two strings are anagrams if they are written using the same exact letters, ignoring space, punctuation and capitalization.
Mar 21, · Write a Java program to check if two String are anagram of each other, is another good coding question asked at fresher level Java Interviews. The first declaration of month is explicit about returning a Month and about not modifying the state of the Date object. The second version leaves the reader guessing and opens more possibilities for uncaught bugs. Example; bad. This loop is a restricted form of std::find. lua_createtable [-0, +1, m] void lua_createtable (lua_State *L, int narr, int nrec); Creates a new empty table and pushes it onto the stack. The new table has space pre-allocated for narr array elements and nrec non-array elements. This pre-allocation is useful when you know exactly how many elements the table will have.
Each letter should have the same count in both strings. Find the first non-repeated unique character in a given string.
This question demonstrates efficient use of Hashtable. We scan the string from left to right counting the number occurrences of each character in a Hashtable. Then we perform a second pass and check the counts of every character. Be prepared for follow-up question for improving memory efficiency, solving it without hash table as well.The following sections describe the standard types that are built into the interpreter.
The principal built-in types are numerics, sequences, mappings, classes, instances and exceptions. Some collection classes are mutable.
The methods that add, subtract, or rearrange their members in place, and don.
To simplify this program, it will be assumed that the first number in the file is an integer which tells the program how many real data points follow. Description. psql is a terminal-based front-end to caninariojana.com enables you to type in queries interactively, issue them to PostgreSQL, and see the query caninariojana.comatively, input can be from a file or from command line arguments.
func MaxBytesReader ¶ func MaxBytesReader(w ResponseWriter, r io. ReadCloser, n int64) io. ReadCloser. MaxBytesReader is similar to caninariojana.comeader but is .
align-content Specifies the alignment between the lines inside a flexible container when the items do not use all available space align-items Specifies the alignment for items inside a flexible container. As I said, there are multiple ways to find if two string are anagram or not. Classical way is getting character array of each String, and then comparing them, if both char array is equal then Strings are anagram.
