Write a c program to reverse a string without using a second array

Also, sort is generic, so that it can be used for any reasonable combination of container type, element type, and comparison criterion. The primary reason that sort tends to outperform qsort is that the comparison inlines better. What is a function object?

How to check if two String are Anagram in Java - Program Example 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. This question is on similar level of finding middle element of LinkedList in one pass and swapping two numbers without using temp variable.

By the way two String are called anagram, if they contains same characters but on different order e. Anagrams are actually mix-up of characters in String. If you are familiar with String API, i.

String than you can easily solve this problem. In this Java program, we will see 3 ways to solve this interview questions, and check if two String are anagram or not. By the way, if you are preparing for Java interview, it's good to prepare some data structures and algorithms questions as well.

More often, there is one or more questions from programming, coding and logic in these interviews.

Java program to check if String is anagram 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.

But before comparing, make sure that both String are in same case e. For simplicity, I have left checking if String is null or empty and converting them into uppercase or lowercase, you can do that if you want.

How to reverse a sentence with C program.

If Interviewer ask you to write production quality codethen I would suggest definitely put those checks and throw IllegalArgumentException for null String or you can simply return false. I would personally prefer to return false rather than throwing Exception, similar to equals method.

Anyway, here are three ways to check if two String are Anagram or not. I have also included a JUnit Test to verify various String which contains both anagram and not.

Test; import static org. First one, takes character array of first String and loop through it, then finds that character in second String, and deletes it by using substring method.

C program, Reversing an array - Stack Overflow

If second String doesn't contains character than method return false immediately. At the end of test if second String is empty than both Strings are anagram because they contains same set of characters.

To improve performance, we have checked length at very start of this method, as two String with different length can not be anagram of each other. Third method is exactly same of first one, except, it uses deleteCharAt int index method of StringBuilder for deleting characters.Algorithm: 1) Declare a character stack S.

2) Now traverse the expression string exp. a) If the current character is a starting bracket (‘(‘ or ‘{‘ or ‘[‘) then push it to stack. C program to Reverse a Sentence Using Recursion This program takes a sentence from user and reverses that sentence using recursion.

This program does not use string to reverse the sentence or store the sentence. strtok - C++ Reference is usually used for string 'tokenizing' (splitting in tokens) - and repeated calls to strtok will give you each time a new token.

While this is perfectly fine if you write single-threaded programs and you don't need the source string . 1 – Introduction Lua is an extension programming language designed to support general procedural programming with data description facilities.

It also offers good support for object-oriented programming, functional programming, and data-driven programming. Today's programming exercise is to write a program to find repeated characters in a ashio-midori.com example, if given input to your program is "Java", it should print all duplicates characters, i.e.

characters appear more than once in String and their count e.g. a = 2 because character 'a' has appeared twice in String "Java".This is also a very popular coding question on the various level of Java. Write a C++ program to reverse the element of an integer 1-D array.
