Uva10755 (Dimension Reduction + scanning) Question:There is A cuboid consisting of A * B * C (Let's calculate the length, width, and height) small blocks. Each small block has its value. It can be positive or negative. If you want to find A cube, the greatest value is;Ideas:First, we need to pre-process the value g [I] [j] [k] to indicate the total value from the height to k, that is, the growth of the k layer to the I, and the width to the j;We can k

province. Get all the intersecting objects on the Y axis in a similar way. The simultaneous intersection in two directions indicates that a collision has occurred in the game.Algorithm time complexity theory is n*n, but in fact there is not so high, the general game, the object is relatively sparse, so it is easy to jump out of the inner layer of the loop.When the object is moving, in order to avoid re-doing the projection operation, you can find the binary search in xlinelist directly, then mo

Dimension-adaptive elements are centered vertically horizontally:If the size of the child element is fixed, then it is easier to set it to vertical horizontal centering, which is not introduced here, specifically, you can refer to the CSS implementation div Horizontal Vertical Center code chapter. If the dimensions of the child elements are not fixed, then setting them to center vertically is a bit cumbersome, as shown in the following code example:DO

PHP Judgment Array Dimension (encapsulated function) Sometimes need to judge the dimensions of the array, surfing the internet to find a lot of things similar to the wording, rambling and do not understand what the meaning of. Here's what I wrote: private static function array_depth($array) { if(!is_array($array)) return 0; $max_depth = 1; foreach ($array as $value) { if (is_array($value)) { $depth =

Thinkphp converts a two-dimensional array into a one-dimensional array method applicable to tags. thinkphp dimension This example summarizes Thinkphp's one-dimensional array method for converting a two-dimensional array into a tag. Share it with you for your reference. The specific implementation method is as follows: Method 1: Copy codeThe Code is as follows: $ projectList = arr1tag ($ projectList, array ('', 'select '), 'Project _ name ');// $ List

Php implements the method of adding values to all one-dimensional arrays in a two-dimensional array. the dimension of the Two-dimensional array This example describes how php adds values to all one-dimensional arrays in a two-dimensional array. We will share this with you for your reference. The details are as follows: Add values (indexes and associations) to all one-dimensional arrays in a two-dimensional array) $ Shop = array (0 => array (0 => 1, 1
