If provided, it must have a shape that the inputs broadcast to. Unfortunately employer who sent this test not willing to disclose test cases to see where is the issue. Maximum value of numpy array (n) Did you check it? The zip() + max() is used to perform the task and it takes O(n) time.Auxiliary Space: O(n) additional space of size O(n) is required, Time Complexity: O(n)Auxiliary Space: O(1). Return the maximum difference. You must write an algorithm that runs in linear time and uses linear extra space. Line-breaking equations in a tabular environment. In the outer loop, pick elements one by one and in the inner loop calculate the difference of the picked element with every other element in the array and compare the difference with the maximum difference calculated so far. Mathematical functions numpy.maximum numpy.maximum # numpy.maximum(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'maximum'> # Element-wise maximum of array elements. Efficient Solution: This solution is based on the idea of Pigeonhole sorting. This is because were using list comprehension + max() + combination() + lambda which has a time complexity of O(n*n) in the worst case.Auxiliary Space: O(n), as were using additional space res other than the input list itself with the same size of input list. If the current element is less than the maximum element found so far and their difference is more than the maximum difference found so far, update the maximum difference with the current difference. If found an empty bucket, The maximum gap would be the difference of maximum value in the previous bucket - minimum value in the next bucket. You will be notified via email once the article is available for improvement. Here, we have to basically find arr[j] - arr[i] such that j gt I. here, we discussed two approaches, one with time complexity of O(n^2) and another efficient approach with time complexity of O(n).In this video, youll also learn about asymptotic notations, they are basically mathematical notations which represent order of growth of any mathematical function. maxDifference doesn't just find the maximum difference from a list, and findNewIndex will actually return the difference result, never an index. I came up with another solution which is as follows: My question is is the second solution correct? I think both of your solutions are correct, but the second one is still at least quadratic O(n^2) since you are performing linear-time operations (such as max()) in your for loop. #DataStructures #Algorithms #DSandAlgo #ProgrammingKnowledge Top Online Courses From ProgrammingKnowledge Python Programming Course http://bit.ly/2vsuMaS http://bit.ly/2GOaeQBJava Programming Course http://bit.ly/2GEfQMf http://bit.ly/2Vvjy4aBash Shell Scripting Course http://bit.ly/2DBVF0C http://bit.ly/2UM06vFLinux Command Line Tutorials http://bit.ly/2IXuil0 http://bit.ly/2IXukt8C Programming Course http://bit.ly/2GQCiD1 http://bit.ly/2ZGN6ejC++ Programming Course http://bit.ly/2V4oEVJ http://bit.ly/2XMvqMsPHP Programming Course http://bit.ly/2XP71WH http://bit.ly/2vs3od6Android Development Course http://bit.ly/2UHih5H http://bit.ly/2IMhVciC# Programming Course http://bit.ly/2Vr7HEl http://bit.ly/2W6RXTUJavaFx Programming Course http://bit.ly/2XMvZWA http://bit.ly/2V2CoAiNodeJs Programming Course http://bit.ly/2GPg7gA http://bit.ly/2GQYTQ2Jenkins Course For Developers and DevOps http://bit.ly/2Wd4l4W http://bit.ly/2J1B1ugScala Programming Tutorial Course http://bit.ly/2PysyA4 http://bit.ly/2PCaVj2Bootstrap Responsive Web Design Tutorial http://bit.ly/2DFQ2yC http://bit.ly/2VoJWwHMongoDB Tutorial Course http://bit.ly/2LaCJfP http://bit.ly/2WaI7ApQT C++ GUI Tutorial For Beginners http://bit.ly/2vwqHSZ Online Courses to learn Data Science - http://bit.ly/2BB3PV8 | http://bit.ly/2IOrpniMachine Learning - http://bit.ly/2J2xex1 Artificial Intelligence - http://bit.ly/2AeIHUR | http://bit.ly/2PCCBEbData Analytics with R Certification Training- http://bit.ly/2rSKHNPDevOps Certification Training - http://bit.ly/2T5P6bQAWS Architect Certification Training - http://bit.ly/2PRHDeFJava, J2EE \u0026 SOA Certification Training - http://bit.ly/2EKbwMKAI \u0026 Deep Learning with TensorFlow - http://bit.ly/2AeIHURBig Data Hadoop Certification Training- http://bit.ly/2ReOl31AWS Architect Certification Training - http://bit.ly/2EJhXjkSelenium Certification Training - http://bit.ly/2BFrfZsTableau Training \u0026 Certification - http://bit.ly/2rODzSKLinux Administration Certification Training-http://bit.ly/2Gy9GQH Follow My Website - http://www.codebind.comDISCLAIMER: This video and description contains affiliate links, which means that if you click on one of the product links, Ill receive a small commission.
