You are given an array of numbers. You need to print the length of the maximum continuous sequence that you encounter. For example if input is [3,8,10,1,9,6,5,7,2 ], the continuous sequences are{1,2,3} and {5,6,7,8,9,10} the latter is the longest one so the answer becomes 6. O(n) solution was asked for, assuming you have a hash map which supports O(1) insertion and fetching operations
