A palindrome is a word, phrase, or sequence of characters that reads the same backward as forward. For example, “racecar” is a palindrome because it is spelled the same way forwards and backwards. A valid palindrome is a palindrome that also meets certain conditions. One common condition is that spaces and punctuation marks are ignored […]

Read MoreThe Three Sum problem is a well-known problem in computer science that involves finding all unique triplets in an array of integers that add up to a target sum. For example, given the array [1, 2, 3, 4, 5, 6, 7] and a target sum of 10, the solution would be [[1, 2, 7], [1, […]
