Char is a type of character, but also a special integer, with single quotation marks for character variables, ' A ', ' 1 ' at the same time ' "is also a character, they do not directly output these special characters, need to escape the help of

For the definition of the stack, the previous statement is prepared.I implemented a stack container class that supports Push,pop,top,size,empty,clear and copy construction operations.The main implementation of the idea is to write a few support

The macro function in C can simplify our operation.However, there are some problems, the macro function can not use ++a/a++,--a/a--this form. This causes the bug (the resulting result is inconsistent with the expected result).The reason is that the

First, the pointerDefining pointer variablesThe data type that the pointer points to * pointer variable name;Example: int *p;Role1. When defining a variable, * is a type specifier, stating that the variable defined is a pointer variable2, when the

Merge sort toO(NlognThe worst time to run, while the number of comparisons used is almost optimal, it is a good implementation of recursive algorithms. The basic operation of this algorithm is to combine two sorted tables because the two tables are

The use of ref and out is simple, and I remember to remind myself to use a better way to write code, not to make the code too bloated, to make people see headaches. Very little code, write directlyThe REF:REF keyword is for arguments to be passed,

Regular expressions are a very important tool and are used extensively in scripting languages such as Perl. It's simple in syntax, but powerful enough to quickly filter out what you want from a lot of strings.Here are some common basic regular

Summary Ranges, summaryranges Question Given a sorted integer array without duplicates, return the summary of its ranges.For example, given [0,1,2,4,5,7], return ["0->2","4->5","7"]. Analysis The question is to represent the number in the vector as
