Check if a Python String Is a Palindrome Using List Slicing One effective method to determine if a string is a palindrome is through list slicing. List slicing is a concise and powerful feature in Python that allows us to extract a portion of a sequence, such as a string. To check if ...
What you want is the first index of the string representation of x. >>> x = 357 >>> str(x) #string representation of x '357' >>> str(x)[0] #first index of that '3' >>> str(x)[2] #third index of that '7' >>> str(x)[0]==str(x)[2] #compare 1st and last Fals...
Give a s, need to check every substring whether it is a palindrome or not. Brute Force T: O(n ^3) 我们利用如果s[start] == s[end], 则只需要判断s[start + 1][end - 1]是否为palindrome即可。 T: O(n ^2) 所以我们利用O(n^2) 的space来提升速度, palin[i][j] 是指s[i : j +...

This tutorial will introduce the methods to check if a string is palindrome or not in C#. Check Palindrome String With theString.Substring()Method inC# A string is considered palindrome if it is read the same forward and backward. Unfortunately, there is no built-in method to check whether ...
The pop() method removes thelast character from the stack. In the last step compare the string and reverseString to check if the string is palindrome or not. importjava.util.Stack;importjava.util.Scanner;classPalindromeTest{publicstaticvoidmain(String[]args){System.out.print("Enter any string...
When the loop is executed get the first index and compare with the last index. func palindrome(string: String)-> Bool{ let char = Array(string) for i in 0..<char.count / 2 { if char[i] != char[char.count - 1 - i] { return false } } return true } Share Follow ...
String.toLowerCase() 要求: palindrome("eye")应该返回一个布尔值 palindrome("eye")应该返回 true. palindrome("race car")应该返回 true. palindrome("not a palindrome")应该返回 false. palindrome("A man, a plan, a canal. Panama")应该返回 true. ...
