This is view of some contiguous amount of memory. If the size is static, this is equivalent to a single pointer, otherwise is it equivalent to two pointers (i.e. begin and end). | |||
If you use this as the parameter to your function, it will accept both arrays and vectors. | |||
Additionaly, there is a [https://en.cppreference.com/w/cpp/container/span/subspan subspan] function so you don't need to pass around indices or pointers to get subvectors. | |||
