If the whole array is consecutive then return null 2. listA has consecutive numbers ListB has no consecutive numbers With numpy diff and sorted. One important fact is we can not find consecutive numbers above N/2 that adds up to N, because N/2 + (N/2 + 1) would be more than N. So we start from start = 1 till end = N/2 and check for every consecutive sequence whether it adds up to N or not. At the same time track the optional letter part. that follow one after another without an interruption: Interest rates have been held at the same level for the tenth consecutive month.
