vector 2 unblocked

See C++primer Plus look bored, the first time do Leetcode practice, originally want to do two-dimensional vector, results always pass, check the reason, must use one-dimensional ...One-dimensional answers:Class Solution {PublicVector{int cout = Nums.size (); Get the size of the vectorvectorfor (int i = 0; i{for (int j = i + 1; j{if ((Nums[i] + nums[j]) = = target){Ret.push_back (i); Get the location of the target valueRet.push_back (j);}}}return ret;}

For example, I have a piece of code as follows: Class cls_vector_item There is no problem with this code. When VCT. push_back (CVI);, when the internal space of VCT is insufficient, a new space will be applied and the object will be removed! However, note that this object should have been removed, but the internal object of the object we are currently in will be removed, but it will become garbage, that is, when the VCT applies for space, the old space is destructed, but our objects are st

For the first time, I said a little bit. The basic content of vector knowledge and a bit of usage skills, the simple display of its role in game programming. This time, take full advantage of the nature of the vector to imitate a physical phenomenon. First, I would like to introduce the two basic but very important techniques that will be used.One, the vector b o

; Besides, by introducing new things like this, Frank D. Luna gave us a bluntness. Let us know from the beginning that this book and the "Dragon Book" second edition is very different.For the convenience of this chapter, the learning objectives are listed here:1. To Learn how vectors is represented geometricallyand numerically. (Learn how to represent vectors using geometric methods and numerical methods.) )2. To discover the operations defined onvect

Chapter 2 Aha! Algorithm Chapter 2nd of programming Pearl River (version 2nd) gave three questions at the beginning. Question B is very interesting: rotating an N-yuan vector to the left to I position. For example, when n = 8 and I = 3, the vector abcdefgh is rotated to defghabc. Simple code uses an N-element intermediate ve
