A binary string is a string consisting of characters 0 In its third sample testcase the sequence given is -2 8 3 8 -4 -15 5 -2 -3 1 and we have to choose the maximum length alternating subsequence , which should be -15,5,-2 . A subsequence of a string is a string which can be obtained by removing several (possibly zero) characters from the original string. For example, if a = [1, 2, 1, 3, 1, 2, 1] a = [1, 2, 1, 3, 1, 2, 1], then possible subsequences are: [1, 1, 1 Your task is to choose maximum by size (length) alternating subsequence of the given sequence (i.
