Gfg time and space complexity
WebMar 14, 2024 · Asymptotic notation is a way to describe the running time or space complexity of an algorithm based on the input size. It is commonly used in complexity analysis to describe how an algorithm performs as the size of the input grows. The three most commonly used notations are Big O, Omega, and Theta. WebMar 31, 2024 · Time complexity: O(n*m) where n is the number of rows and m is the maximum number of elements in a row. Auxiliary space: O(k) where k is the number of even-length rows in the list. Method #4:Using the reduce() function and a lambda function: Algorithm: Initialize an empty list ‘res’ to store rows with even length strings.
