Let F (n) denote the furthest distance we can go with n steps, then we can derive this formula easily: F (n) = (n + 1)/2) ^ 2 if n is odd, (1, 2, 3, 4, 3, 2, 1) F (n) = (n/2) ^ 2 + n/2 If n is even. (1, 2, 3, 3, 2, 1) Give the distance of F (N), we

In the previous period, the author briefly introduced some basic knowledge about VBScript, one of ASP scripting languages. In this period, I will continue to explain how to compile VBScript, by presenting a series of examples of VBScript in ASP

Math. Abs () calculates the absolute value. Math. ACOs () calculates the arccosine value. Math. asin () calculates the arcsin value. Math. atan () calculates the arc tangent value. Math. atan2 () calculates the point-to-point angle from the X

Return the value of N1 rounded to the right of the decimal point. The default value of N2 is 0. This is the nearest integer to the decimal point. If N2 is a negative number, it is rounded to the corresponding digit on the left of the decimal point,
