std::vector<int> vec = {1, 2, 3};
vec.resize(2); // {1, 2}
vec.resize(4); // {1, 2, 0, 0,}
vec.resize(6, 9); // {1, 2, 0, 0, 9, 9}dp.resize(n+1,vector<vector<int>>(n+1,vector<int>(n+1,-1)));
resize (size_type n, const value_type& val);
The resize() method (and passing argument to constructor is equivalent to that)
will insert or delete appropriate number of elements to the vector to make it
given size (it has optional second argument to specify their value). The C++ function std::vector::resize() changes the size of vector. If n is smaller than current size then extra elements are destroyed.
If n is greater than current container size then new elements are inserted at the end of vector.
If val is specified then new elements are initialed with val.| Code Example |
