WebThe complexity for string::size ()/length () is constant but of course it would be faster to store size in a variable (e.g. sz) because of: -Accessing ( sz) is faster than accessing ( … WebIn general, concatenating two strings will be linear in lengths of both strings. However, if the first string is an rvalue, then the second one will be just appended to it. If appending doesn't cause the first string to reach its capacity, you can expect it to take time proportional to the length of the second string.

WebRabin-Karp algorithm is an algorithm used for searching/matching patterns in the text using a hash function. Unlike Naive string matching algorithm, it does not travel through every character in the initial phase rather it filters the characters that do not match and then performs the comparison.
