An Excel form is used to make a summary of the student's test scores, as shown in Figure 1. You need to rank according to the results of the corresponding account in the AA column and place the results in the corresponding cells in the AB column.
NumberThis type is used to represent integers and floating-point values. The typeof operator can determine the type of number. There is also a special value, NaN (non-numeric not a number), which is used to denote a case where an operand that would

A thorough study of C-language algorithm for fast Fourier transform FFT
LED music spectrum display of the core algorithm is fast Fourier transform, FFT understanding and programming is more difficult, specially write this article to share the
ECMAScript is a dynamically typed language built on the basis of 5 simple data types (Undefined, Null, Boolean, Number, String), and a complex data type (Object). This article will review the simple data type, I will try to describe from the
Problem Description:
Find the largest palindrome made from the product of two n-digit numbers.Since The result could is very large, you should return the largest palindrome mod 1337.
Example:
Input:2output:987explanation:99 x 91 = 9009, 9009% 1337
In daily life, random numbers are actually often encountered, want to throw dice, lottery, and draw lots. Oh, very simple can be achieved. So in doing programming, really to design a random number through their own program that is really not easy.
% is the remainder operation
123% 9 = 6
(1+2+3)% 9 = 6
3456795% 9 = 3
(3+4+5+6+7+9+5)% 9 = 3
(-123)% 9 = 3
[-(1+2+3)]% 9 = 3
Will be credited as a1a2a3 ... An, the divisor is 9, the remainder is recorded as Q.
Then there are:
A1a2a3 ...
