WebApr 28, 2024 · As for your memory complexity, your intuition is right for an 8-bit integer.However, if we are talking about primitive datatypes, you can simply think of them as constants. Thus, you should be rather concerned about complex datatypes i.e. an array, since it aggregates multiple primitives.
WebT (N) = Time Complexity for problem size N T (n) = Θ (1) + 2T (n/2) + Θ (n) + Θ (1) T (n) = 2T (n/2) + Θ (n) Let us analyze this step by step: T (n) = 2 * T (n/2) + 0 (n) STEP-1 Is to divide the array into two parts of equal size . 2 * T (n/2) --> Part 1 STEP-2 Now to merge baiscall traverse through all the elements. constant * n --> Part 2 WebTime complexity of an algorithm signifies the total time required by the program to run till its completion. The time complexity of algorithms is most commonly expressed using the big O notation. It's an asymptotic notation to represent the time complexity. We will study about it in detail in the next tutorial.
