What are the different way of reversing a string?

Reverse a String in Java in 10 different ways

• Using StringBuilder/StringBuffer.
• Using Stack.
• Using Java Collections Framework reverse() method.
• Using character array.
• Using character array and swap()
• Using + (string concatenation) operator.
• Using Unicode Right-to-left override (RLO) character.
• Using a Byte Array.

Which is best suitable for reversing a string?

Explanation: Stack is the most appropriate data structure for reversing a word because stack follows LIFO principle. Operations required for reversing a word or a string using stack are push() and pop(). Explanation: Push operation inserts a character into the stack and pop operation pops the top of the stack.

How do you reverse a string that has changed positions?

Mark the space position of the given string in this string. Insert the character from the input string into the result string in reverse order. While inserting the character check if the result string already contains a space at index ‘j’ or not. If it contains, we copy the character to the next position.

How do I reverse a string without special characters?

Simple Solution:

1. Create a temporary character array say temp[].
2. Copy alphabetic characters from the given array to temp[].
3. Reverse temp[] using standard string reversal algorithm.
4. Now traverse input string and temp in a single loop.

How do I reverse a string pointer?

Given a string, the task is to reverse this String using pointers. Approach: This method involves taking two pointers, one that points at the start of the string and the other at the end of the string. The characters are then reversed one by one with the help of these two pointers.

How do I reverse a string function?

Method 1: Reverse a string by swapping the characters

1. Input the string from the user.
2. Find the length of the string. The actual length of the string is one less than the number of characters in the string.
3. Repeat the below steps from i = 0 to the entire length of the string.
4. rev[i] = str[j]
5. Print the reversed string.

What’s the best way to reverse a string?

Using inbuilt “reverse” function: There is a direct function in “algorithm” header file for doing reverse that saves our time when programming. Reverse string using the constructor : Passing reverse iterators to the constructor returns us a reversed string.

How to reverse a string object in JavaScript?

Reverse a String With Built-In Functions 1 The split () method splits a String object into an array of string by separating the string into sub strings. 2 The reverse () method reverses an array in place. The first array element becomes the last and the last becomes the first. 3 The join () method joins all elements of an array into a string.

How to reverse a string using swapping logic?

Then a user-defined function, revAString () is declared and in its definition, reversing the string using swapping logic is written. First of all, you take g (a counter variable), a variable numb of type integer and a temporary variable (name tmpry) used for swapping and initialize this temporary variable with 0.

How to print the reverse of a string in Java?

Using built in reverse () method of the StringBuilder class: String class does not have reverse () method, we need to convert the input string to StringBuilder, which is achieved by using the append method of StringBuilder. After that, print out the characters of the reversed string by scanning from the first till the last index.
