How do you reverse a string without reversing?

Given a line of text, reverse the text without reversing the individual words. A simple solution is to push the individual words from the beginning of the text into a stack. Then, pop all the words from the stack and store them back into the text in LIFO order.

How do you reverse a string in C#?

To do this, we use the ReverseString method of the SringHelper class to collect the input string parameter which we want to reverse, convert that string into an array using the ToCharArray method and then call on the Reverse method to change the order of the letters in that string.

What method is string class allows to reverse the given string?

Reverse a String using String Builder / String Buffer Class. StringBuffer and StringBuilder comprise of an inbuilt method reverse() which is used to reverse the characters in the StringBuffer. This method replaces the character sequence in the reverse order.

How do I reverse an array pointer?

Approach : In reverse function we take two pointers one pointing at the beginning of the array, other pointing at end of the array. The contents of the memory location pointed by these two pointers are swapped and then the value of first pointer is increased and that of second pointer is decreased .

How can I use sentence in C?

Is palindrome a string?

A string is said to be palindrome if it reads the same backward as forward. For e.g. above string is a palindrome because if we try to read it from backward, it is same as forward. One of the approach to check this is iterate through the string till middle of string and compare a character from back and forth.
