Program 3: Using for loop/While loop and String function charAt This is really a simple program. You just need to have a basic understanding offor loopandif..else statementto understand this program. Here, we are iterating over the string in reverse order (from length-1 to 0) and readin...

使用forloop的scala回文函数 、、 我想知道Scala中Java回文函数的等价物,在scala中编写带有多个变量的forloop是很棘手的 class Solution { public boolean isPalindrome(String s) { for (int i = 0, j = s.length() - 1; i < j; i++, j--) { while (i < j && !Character.isLetterOrDigit(s....
Code Output Let’s consider the input string python. This Python program correctly recognizes radar as a palindrome and python as not a palindrome using the loop method, emphasizing the versatility of different approaches for palindrome checks in Python. Check if a Python String Is a Palindrome U...
Base case: When one of the strings is empty, all characters from the other string need to be deleted in order to make them equal. Time complexity: O(n^2). Scala code: def kPalindrome(s: String, k: Int): Boolean = { val rev = s.reverse val n = s.length val dp = Array....
For linear solution, you can use Manacher's algorithm. There is another algorithm call Gusfield's Algorithm, and below is the code in java: public class Solution { char[] temp; public int match(int a, int b,int len){ int i = 0; while (a-i>=0 && b+i<len && temp[a...

That's all about how to check for palindrome in Java. You have learned how to find if a given String is palindrome using Recursion as well by using StringBuffer and for a loop. More importantly, you have done it by developing your own logic and writing your own code i.e. not taking...
The program will prompt user to input the number and then it will reverse the same number using while loop.Reverse number in Java using for loop This code will be a lot longer than other examples we have, but we have commented it so it is easy to follow. What we did is extract the...
