How much space does construction of suffix tree takes?(a) O (log M)(b)

1.	How much space does construction of suffix tree takes?(a) O (log M)(b) Exponential to Length of Tree(c) O (M!)(d) Linear to Length of TreeOrigin of the question is Suffix Tree topic in section Trie of Data Structures & Algorithms IThis question was addressed to me at a job interview.
Answer» Correct option is (d) Linear to Length of Tree The explanation is: Suffix tree is also KNOWN as PAT tree or position tree. It is a compressed search tree or prefix tree in which keys contain the suffix of text VALUES as the text position. It allows fast string operation. TOTAL SPACE taken for construction of a suffix tree is linear to the length of the tree.
