Javascript (1) Summary of javascript Array usage (1) /* 1. The js array, like the arrays in other languages, is an ordered list of data, but the difference is that each item of the js array can save any type of data. In addition, the js array size can be dynamically adjusted. 2. Create an Array: * // (1) Use the Array

usually uses the viewport attribute of the graphicsdevice class to obtain the screen size. This is accessed through the graphicsdevice attribute of the game and provides the width and height attributes. Then, the textposition -- point corresponding to the top left corner of the viewport is calculated as the upper left corner of the displayed text string. (It is then straightforward to calculate textposition-the point relative to the upper-left corner of the viewport where the upper-left corner

than W. from all such subsets, pick the maximum value subset. 1) Optimal Substructure:To consider all subsets of items, there can be two cases for every item: (1) the item is encoded in the optimal subset, (2) not supported ded in the optimal set.Therefore, the maximum value that can be obtained from n items is max of following two values.1) Maximum value obtain

We know that a function f can obtain a random number ranging from 1 to 5 with equal probability. How can we obtain a random number ranging from 1 to 7 with equal probability? Int rand7 (){Int;While (A = rand5 () * 5 + rand5 ()> 26 );Return (A-3)/3;} AlgorithmThe idea is:1. Use rand5 () * 5 + rand5 () to generate 6 7 8 9 10 11 ...... 26, 27, 28, 29,

According to PRIM 0, PRIM 1 ,... prim k, find the smallest prime number prim k + 1 (here is based on the prime number to find the prime number) 23 if prim k + 1 is greater than N, then, prim k is the prime number we need to find. Otherwise, we will continu

At first, the computer operating system was 32 bits, and the time was expressed as 32 bits. (Integer. MAX_VALUE );2147483647 Integer is expressed in 32 bits, so the maximum value expressed in 32 bits is 2147483647. In addition, the total number of seconds for the second day of the year is 365, 2147483647/31536000 = 68.1 That is to say, the maximum time that 32 bits can represent is 68 years. In fact, by, January 1, January 19, 2038Seconds, the max
