How can implement a C++ vector that points to other, multiply typed vectors?

I want to store elements of multiple types in a single vector, while keeping elements of the same type contiguous. The types are derived from a base class and I expect different types to be implemented throughout the development cycle. For this…

Longest Common Contiguous Substring Length in C

So the following is the code I wrote up for the algorithm. I cannot find what is wrong with it. The test cases are supposed to yield 12, 4, and 3 respectively but instead yield 8, 1, and 2 respectively. Did I misunderstand the algorithm…

Count fragments or sequence of contiguous numbers in an array

Say you have an array of integers, eg: [0,1,2, 5,6,7, 9,10,11]. In an ideal world they would be sorted, but if the algorithm can work with unsorted, even better. I need to know how many "fragments" are in this group. Imagine the array makes up an…
