![]() ![]() We’ll pass strings with varying formats, such as “racecar”, “RaceCar”, and “race CAR” among others. You’ll need to remove all non-alphanumeric characters (punctuation, spaces and symbols) and turn everything lower case in order to check for palindromes. In today’s project, you will learn four different ways to identify a potential palindrome. For example: desserts, which is stressed backward, or vice versa. Compare the flipped (reversed) letters with the original. Semordnilap (palindromes spelled backward)also known as: word reversals, reversible anagrams, heteropalindromes, or a semi-palindromespell a different word in reverse. ![]() Otherwise, return false.Ī palindrome is a word or sentence that’s spelled the same way both forward and backward, ignoring punctuation, case, and spacing. There are really only two things that I need to do to identify a palindrome: Flip the word. Algorithm Challenge Return true if the given string is a palindrome. Code : num cdbl(inputbox('Enter a number to check palindrome'))temp numdo while num (greather than) 0 remainder num mod 10 reverse (reverse10) + rem. In this article, I’m going to explain two approaches, first with built-in functions and second using a for loop. ![]() The word “palindrome” was first coined by the English playwright Ben Jonson in the 17th century, from the Greek roots palin (“again”) and dromos (“way, direction”). This article is based on Free Code Camp Basic Algorithm Scripting “ Check for Palindromes”.Ī palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward. ![]()
