a little bit of performance loss. 6. The foreach before php7 is actually copying a copy out and then looping. This time I still recommend using Array_map (), Array_walk (), Array_filter () and other functions to handle your problem. 7. $dir = DirName (dirname (dirname (__file__)); This optimization method I wrote is: $dir = Realpath (__dir__. '/.. /.. /'); The last directory to be determined must exist, otherwise it will return false 8. Be sure to understand the difference between = = and =

The difference between the iteration method and the binary method is that the iteration method makes full use of the value of R. The time is greatly reduced. My iteration time is 47 ms.The Code is as f

Question: there is a full binary tree. Each node is a switch. It is closed at first, and the ball falls from the vertex, Each time the ball goes through the switch, it will reverse its status. Now, I want to ask the Switch number that the K ball goes through when it falls to layer D. Analysis: hexadecimal encoding. After several simulation times, we can see that the ball will make the switch form a continuous binary number representation (the root is low ). When the k-th ball is placed, the s

)The following figure illustrates how to test 5 times with 3 eggs, to solve the 21-storey problem, where the rule is that for independent testing, if the test is broken, a subsequent test is performed on the lower floor, and if it is not broken, follow-up tests are performed on the high floor, where the brackets represent the floor/floor range of the test execution.In fact, for the case of D (n,m-1) Postscript: This is an article of foreign cattle, for the problem of throwing eggs

The main topic: Give a completely binary tree, each node has a switch, just start the switch is open, the ball passes through the node after the switch is closed (except the root node). If the ball passes through the node's sibling node, then the switch on the node opens again.Now put the ball to the root node, preference to the left node to go, if the left node switch off, select the right. After the ball falls to the leaf node, the other ball continues, asking the nth ball to which leaf node i

Title: There is a complete two-fork tree, each node is a switch, initially completely closed, the ball is discarded from the vertex.Each time the switch ball is reversed. Now ask the K ball to drop to D when the layer switch is number.Analysis: Binary encoding. After several simulations, the ball will let the switch form a continuous binary number representation (the root is low).When you put the K ball. The switch state is exactly the binary K.
