Your task is to find the first element of an array that is not consecutive. If you have a sequence in either the number or letter part or both, do the range merge once one of them is broken. The part where it gets complex is when there are two or multiple digit numbers. Write Java code to count the number of characters which gets repeated 3 times consecutively and return that count (ignore case). To count the number of such subsets, we need to count the consecutive numbers such that difference between them is not equal to one. The For loop is to iterate from 1 to maximum value (Here, number = 5). This may or may not be what you want. Let this count be c.

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. Re: Consecutive numbers in java? Count consecutive characters in a string java.
