Hello,
please help me to prove that:
O(max(f1(n),f2(n),...,fk(n))) = O(f1(n) + f2(n) + ... + fk(n))
thank you

The Maximum Rule in Big O Notation is a mathematical concept used to analyze the efficiency of algorithms. It states that in a series of mathematical expressions, the overall growth rate is determined by the term with the highest growth rate.
The Maximum Rule is important because it allows us to quickly determine the time complexity of an algorithm by focusing on the term with the highest growth rate. This allows us to compare and analyze the efficiency of different algorithms and choose the most efficient one for a given problem.
To prove the Maximum Rule, we need to show that the term with the highest growth rate dominates the overall growth rate of the expression. This can be done through mathematical induction or using the limit comparison test. By showing that the term with the highest growth rate becomes significantly larger as the input size increases, we can prove that it is the dominant term.
The Maximum Rule considers the term with the highest growth rate as the dominant term, while the Simplified Maximum Rule only considers the highest degree term. This means that the Simplified Maximum Rule may not always provide an accurate analysis of the efficiency of an algorithm, as it ignores any lower degree terms that may still contribute significantly to the overall growth rate.
Yes, the Maximum Rule can be applied to any algorithm that has a time complexity expressed in terms of an input size. However, it may not be the most efficient approach for some algorithms, as it only considers the asymptotic behavior and not the actual runtime of the algorithm. Other factors such as memory usage and data structure also play a role in determining the efficiency of an algorithm.
