'+ 1 ':Int (math. sqrt (I) outputs the largest integer smaller than I's square.
For example, math. sqrt (51) results are larger than 7, while int (math. sqrt (51) outputs 7In addition, in range (m, n), the range () function generates a list of integers from m to n-1. Therefore, you must '+ 1' to complete the operation.
By the way, the range () function.

Multi-threaded concurrent programs and collaborative programs are actually different concepts. Multi-thread concurrency means that multiple execution sequences run at the same time, while the collaborat

Example of several methods for deleting elements in an array in Javascript loop: javascript Array

bit of thinking, I decided to let C + + also have the ability to use a Foreach loop.C + + macros are good for this kind of thing. The problem is how to do it more like the style in C #. If you add a macro to the front and back of the code block that accesses the element, then this thing becomes meaningless and ridiculous.We can only use one macro and name it foreach. The code block behind this macro will be able to use a variable name to traverse all elements in the container, as in C #. Variab
