What is the time complexity for deleting the string to form a new string in the rope data structure?(a) O (n^2)(b) O (n!)(c) O (log n)(d) O (1)This is a very interesting question from Binary Trees in portion Binary Trees of Data Structures & Algorithms IThis question was posed to me in my homework.

Answer»

Correct choice is (c) O (log N)

For EXPLANATION: In order to perform the deletion on the rope DATA structure, ONE can delete the given string at any position x to form a new string in O (log n) time. So, the time complexity for worst case is O (log n). This can be done by TWO split operations and one concatenation operation.
