If it is true then arr[0] is to be returned, because there is no decreasing step available to find an alternating subsequence. Participants with rank 11 to 100 (both inclusive) receive rupees Y each. Compilation Error Posted: (2 days ago) Application Afterwards there is a survey Applied online, 20 min phone call with a recruiter (non-technical), and then got sent a general coding test via CodeSignal (~1 hour . Remember we have chosen las[j][1] + 1 not las[j][0] + 1 to satisfy alternate property because in las[j][0] last element is bigger than its previous one and A[i] is greater than A[j] which will break the alternating property if we update. Your task is to choose maximum by size (length) alternating subsequence of the given sequence (i.e. I understand the dp solution but I fail to understand why adding the first number in the array then adding every positive arr[i] arr[i-1] works if you have to choose numbers starting from the first element.
