Divide and conquer algorithm to find maximum. Design and Analysis Max-Min Problem

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?

 

if (l==r) return a[l]; //trivial case, if there is only one value in the array return it int m=(l+r)/2; //find value halfway into the array int.Improving the first-time asker experience - What was asking your first

Kadane's Algorithm and Its Proof - Max/Min Sum Subarray Problem. Using Divide and Conquer approach, we can find the maximum subarray sum in O (nLogn).So total no.

 

The Max-Min Problem in algorithm analysis is finding the maximum and minimum value in an array. Solution. To find the maximum and minimum.Be the first to rate this post.

 

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.
