\nFollowing are steps to search a pattern in the built Trie.
\n1)<\/strong> Starting from the first character of the pattern and root of the Trie, do following for every character.
\n\u2026..a)<\/strong> For the current character of pattern, if there is an edge from the current node, follow the edge.
\n\u2026..b)<\/strong> If there is no edge, print \u201cpattern doesn\u2019t exist in text\u201d and return.
\n2)<\/strong> If all characters of pattern have been processed, i.e., there is a path from root for characters of the given pattern, then print print all indexes where pattern is present. To store indexes, we use a list with every node that stores indexes of suffixes starting at the node.<\/p>\n[ad type=”banner”]\n\/\/ A simple C++ implementation of substring search using trie of suffixesSearch for 'ee'\r\nPattern found at position 9\r\nPattern found at position 1\r\n\r\nSearch for 'geek'\r\nPattern found at position 8\r\nPattern found at position 0\r\n\r\nSearch for 'quiz'\r\nPattern not found\r\n\r\nSearch for 'forgeeks'\r\nPattern found at position 5\r\n<\/pre>\n
