演算法學習-數字連續的子陣列

題目

給定長度為N的陣列A[0...N-1],求遞增且連續數字最長的子陣列。

如陣列：1,2,3,34,56,57,58,59,60,61,99,121的連續數字最長的一段位56,57,58,59,60,61.

程式碼

int MaxSequence(const int* a, int size, int& from, int& to)
{
	int* p = new int[size];
	int i;
	for (i = 0; i < size; i++)
	{
		p[i] = 1;
	}
	int m = 1;
	for (i = 1; i < size; i++)
	{
		if (a[i] - a[i - 1] == 1)
		{
			p[i] += p[i-1];
			m = max(p[i], m);
			to = i;
		}
	}
	from = to - m + 1;
	delete[] p;
	return m;
