Yang Hui triangle properties:
Each line of numbers is symmetric between the left and right, and gradually increases from 1, then decreases, and returns to 1.The number of numbers in the nth row is n.The number in line n is 2 ^ (n-1 ).Each number is equal to the sum of the left and right digits of the previous row. This pr
Given numrows, generate the first numrows of Pascal ' s triangle.For example, given numrows = 5,Return[ 1], [ 1,2,1], [ 1,3,3,1], [ 1,4,6,4,1]Analysis: This problem is actually showing the characteristics of Pascal Triangle: it is a triangular matrix, its top is 1, as (row0). Line 1th (row1) (11) Two 1, these 1 are the sum of two numbers above them (not within the triangle as 0). And so on, the re

Here, he first designed and implemented the PASCAL Language (abbreviation of PHILIPS Automatic sequence Calculator Language), which was successfully developed on CDC 6600. Pascal has many creations in terms of data structure and

It is thought that the reason why C is strong, and its freedom, is largely reflected in its flexible use of pointers. Therefore, it is not too important to say that the pointer is the soul of C language. At the same time, this argument also makes a lot of people misunderstanding, it seems that only the C language pointer can be counted. Basic does not support pointers, regardless. In fact, the Pascal language itself also supports pointers. The Object
The original PASCAL Language was built on some simple concepts that are now widely used inProgramming Language. The most important concept is the data type. The data type determines the valid values of the variable and the operations that can be performed on these values. The concept of Pascal data type is stronger than that of C language and basic language in the early days. In C language, arithmetic data
Note
In PASCAL, annotations are enclosed in braces or parentheses with asterisks. Delphi also recognizes C ++-style comments, that is, the comments are placed behind the double slashes. For example
{This is a comment} (* this is another comment *) // This is a comment up to the end of the line
The first method is simple and widely used. The second method is widely used in Europe because the European keyboard lacks braces; the third method of a
We all think that the reason why C language is powerful and its freedom is largely reflected in its flexible pointer usage. Therefore, pointer is the soul of the C language, and it cannot be said at all. At the same time, this argument has caused many people to misunderstand. It seems that only pointers in the C language can calculate pointers. Basic does not support pointers. In fact, Pascal supports pointers. From the initial development of
