How to convert the color vector map to grayscale, while ensuring that each part retains the character of the vector graph? Don't forget, CorelDRAW also have filters, we try it!
1. First, enter a color vector in the CorelDRAW, as shown in figure:
2. Press ALT+F3 to open the Filter dialog box and press F6 to draw a rectangle larger than the color

Similarities and differences.
For natural language the same pointare based on distribution ideas using the same corpus distributional models (Bow,lsi,lda)Altogether now the same text area morphemes (such as the same statement) related, the more common statements in the corpus, the more relevant to use the number of common statements to construct words and words
the container to be reserved. The resize function can have two parameters, the first parameter is the new container size, and the second parameter is to add new elements in the container. If this parameter is omitted, the default constructor of the element object is called. The following are examples of the two functions:
???? Vector
Because the source code of the two interfaces is quite simplified, You can paste them here:

Use vector containers, that is, to avoid the search, so today we list some STL find algorithm applied to the vector.
Find ()Returns an iterator to the "the" in the range [First,last] that compares equal to Val. If no such element is found, the function returns last.
#include
find_end () searches the range [first1,last1) for the "Last occurrence of" sequence defined by [ FIRST2,LAST2), and returns a i

The data structure we implement is to solve the dynamic open-up space usage during the running process (for example, we do not know how much we enter without stopping the input)
Two principles:
I. Stupid Methods
How much space is used and how much space is opened for the first time?
The second time we use space, we will open up space B larger than the first one, copy the data in A to B, then release a, and write new data in C.
Disadvantage: copying is too many times and the efficiency is lo

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
