Summary<\/span><\/h2> \n

NASA\u2019s latest radar technology captures shape signatures of flying objects as strings of characters. As everyone knows, UFO\u2019s are shaped like saucers and are therefore symmetrical. If a radar signal string is a Palindrome then it is symmetrical and represents a UFO. A palindrome is a word, phrase, number, or sequence of characters that reads the same forwards and backwards.<\/span><\/p>","category":["Classicist TDD","Beginner"],"pubDate":"Thu, 10 Jul 2025 09:29:49 GMT","guid":"https:\/\/www.codurance.com\/katas\/palindrome-radar"},{"title":"Morning Routine","link":"https:\/\/www.codurance.com\/katas\/morning-routine-kata","description":"
