![]() ![]() ' Shortcut: we can abort on the first mismatched character we encounter, no need to check further. ![]() so this ignores the middle character if the string is an odd-number of characters long. #Vbscript program for palindrome checking mod' Note that integer division results in a truncated value, e.g. Best answer Write a shell script to find a number is palindrome or not A palindrome number is a number that is same after reverse. Code : num cdbl(inputbox('Enter a number to check palindrome'))temp numdo while num (greather than) 0 remainder num mod 10 reverse (reverse10) + rem. ' Only need to iterate until half of the string length. For every visited node, pop a node from the stack and compare data of popped node with the currently visited node. Traverse the given list from head to tail and push every visited node to stack. Write a program to check whether a given number is a palindrome or not Write a program to check whether a given number is a. OR its only divisible by 4 not by hundred. The logic is that the year is either divisible by both 1. ![]() ' Shortcut case if the input string is empty. Value = value.Replace(" ", "") // Note String.Replace(String,String) runs in O(n) time and if replacement is necessary then O(n) space. If value Is Nothing Then Throw New ArgumentNullException("value") Private Sub btnCheckPalindromeClick (ByVal sender As Object, ByVal e As System.EventArgs) Handles btnCheckPalindrome.Click Dim intPosition As Integer Dim strText As String Dim strResult As String strText Me.txtEnterPalindrome. In VB.NET: Public Shared Function IsPalindrome(value As String) As Boolean The optimal algorithm for checking a palindrome needs only iterate through half of the input string - by comparing value with value for n = 0 to length/2. However consider the essential properties of a palindrome: the first half of a string is equal to the second half of the string in reverse. NET) (plus extra iterations for your Trim and Replace calls). for-loop reverses the string and stores the reversed string in reversed variable. #Vbscript program for palindrome checking fullWhile using string reversal works, it is suboptimal because you're iterating over the string at least 2 full times (as string reversal creates a copy of a string because strings are immutable in. ![]()
