Machine Learning Guidance. Now the critical question is: can we solve the problem using another approach? The number of comparisons can be reduced using the divide and conquer approach. The main idea is that if we divide the array in 2 subarrays, then the maximum must be in the left or in the right part of the array; there's no other possibility. Refer us to your friends and help us grow. Does this algorithm always work? Is there any other way to solve this problem?

We can easily solve this problem by using Divide and Conquer. The idea is to recursively divide the array into two equal parts and update the maximum and.The proper test is to look at the difference between the upper and the lower bound:.

Divide and Conquer Approach In this approach, the array is divided into two halves. Then using recursive approach maximum and minimum numbers in each halves.This leaves us with the problem of detecting a range of length 1.

Divide the problem into number of smaller units called sub-problems. · Conquer (Solve) the sub-problems recursively. · Combine the solutions of all the sub-.On the basis of comparison: Compare the larger element with max, update max if required.

What is the (worst case) number of comparisons in Algorithm A?. It should be clear that any algorithm for finding the Max is Ω(n). Thus, the above algorithms.To find the maximum and minimum numbers, the following straightforward algorithm can be used.

By induction we find T(n)=(3n/2)−2, for n a power of 2. Integer Multiplication. The standard multiplication algorithm takes time Θ(n2) to multiply together two.So we find the maximum in the left part, we find the maximum in the right part and the global maximum will obviously be the maximum between the two maximum, that is what is returned by the last line of the maxsimum function.
