-A)/len + 1 BucketsFor any integer K in an array, it is easy to find the position of the bucket by using the equation loc = (k-a)/Len, and then maintain the maximum and minimum values for each bucketBecause the difference between elements in the same bucket is at most len-1, the final answer will not be selected from the same bucket.For each non-empty bucket p, find the next non-empty bucket Q, then Q.min-p.max may be an alternative answer. Returns the maximum value in all of these possible valu

Memory testing is more boring, at present in the major hardware, the frequency of memory is often the most easily overlooked, but is the capacity of memory, more than the frequency of memory to be more concerned about a bit higher. Of course, how much memory capacity for the best, is 16G or 8G, or 4G, or to see the user's use of the habit, and now someone is still in the 1g,2g to use, is not a strange thing. To sta
Gossip does not say, on the question: A large PHP array (1w+), using Array_shfit and array_pop to take array elements, the performance gap is particularly large, array_shift slow unbearable, and Array_pop quickly. Don't say the answer first, look at the paragraph code: $arr = Array (0=>123, 3=>132, 2=>987,) Array_shift ($arr);//array_pop ($arr); Var_dump ($arr); What is the difference in output? After Array_shift, the output is: Array (2) { [0]=> Int
1. Set a parent element for the Inline-block element.
Sets the font-size:0 of the parent element;. The child element font-size is set to the appropriate size, and if the child element font-size is not set, the child element inherits 0 of the parent element;
2. Set a parent element for the Inline-block element. (letter-spacing: Character spacing)
Set the parent element's letter-spacing to -4px or -8px, except Google is -8px and the rest is -4px. Also set the letter-spacing:0 of the child eleme
The Difference border property (border) is used to set the edge of an element.
Margin attributes (margin) are used to set the distance between the edges of an element's space and the adjacent elements.
The gap attribute (padding) is the distance used to set the content of an element to the bounds of an element.
These three properties belong to the box type property in the CSS.
The following diagram, very vividly embodies the difference between the t

This article mainly introduces InnoDB gap locks in MySQL, reminding users to pay attention to deadlocks, for more information about how to troubleshoot deadlocks for a customer, I encountered an interesting situation including InnoDB gap locks. In non-insert write operations WHERE a WHERE clause does not match any rows, I expect that the transaction will not have a lock, but I am wrong. Let's take a look at
Today, when you add constraints to your view to compare previously added constraints, there are two layers of light red wireframe a solid line and a dashed line, whereas the previous demo added only a solid blue wireframe.The constraint 1 added today is as follows:Figure 1As previously added, constraint 2 shows:Figure 2Later, when you add a button to the first constraint under a peer view, the Discovery button leaks part of the=This problem does not occur if you are constrained in the second way
Bandgap voltage reference, often someone simply calls it bandgap. The most classic bandgap reference is the use of a voltage proportional to the temperature and an inverse temperature of the sum of the voltage, the two temperature coefficients offset each other, to achieve temperature-independent voltage reference, about 1.25V. The bandgap provides a reference voltage to the OSC.Reference documents:[1] The design of the bandgap. Http://www.eetop.cn/blog/html/90/757190-24701.html[2] band
