If there were not, we would have to backtrack another step and erase Ore, replacing it with another word that starts with or. There are a few more technical details. For example, whenever I choose a word, I need to record it so that I don't use it again (but un-record it when...
that is I use a hashmap of already all prefixes pointing to the indexes of the words where the prefix is from. The value of the Map is a sorted tree, so it can be really easily determined which word with the common prefix is closest to the current index. The HashMap ensures...

First, we identify the unique prefixes for fields F1 and F2 that are shown in Figure 15.12. Using these unique prefixes, we build two binary tries, one for field F1 (F1 trie) and the other for field F2 (F2 trie). Each node containing a valid prefix is associated with a bit vector ...

Idea is similar to shortest palindrome, we need to create a trie that reflects the reverse of all words. We match head and tail first, the rest of string/substring should be a palindrome. publicclassSolution {classTrieNode { TrieNode[] children=newTrieNode[26];intwordArrayIndex = -1;//...
A square whose first location starts with the last occurrence of two distinct squares is an FS-double square. We explore and identify the conditions under which a sequence of locations in a word starts with FS-double squares. We first find the structure of a wo...
In 2016, the word “abortion” was mentioned 35 times in the document, while the 2024 platform only has it once. This year's platform declares the decision should go to the states, veering away from a national abortion ban. That’s come with some backlash — anti-abortion advocates...
