(15 pts) Write a function longestSequence (X) which accepts an array of positive numbers X and returns the length of the longest array containing successive numbers from the array X. The following table shows a possible list of outputs of the function longestSequence (X). Function call longestSequence ([1, 4, 10, 2, 3, 1, 2, 6]) longest Sequence ([20, 11, 13, 13, 12, 9, 1, 10, 14]) longestSequence ([8, 9, 7, 5, 3, 8, 8, 4]) Output 4 6 3 Table 1: A list of possible outputs of the function longestSequence
