03rd-startup screen: Today, we are going to learn a very small knowledge point, but it is a very important part of the application lifecycle: the startup screen. You may think this is a poor theme, but in fact, it is very important from the perspective of user experience.For example, a weather application connects to a network and obtains weather data. Every time you start this program, you want to obtain the latest data. You also know that it takes about 2-3 seconds to obtain data, correct ima

[Sword refers to Offer learning] [interview question 31: the largest sum of consecutive sub-arrays], sword refers to offerQuestion: enter an integer array with a positive or negative number in the array. One or more consecutive integers in the array form a sub-array. Returns the maximum value of the sum of all sub-arrays. The time complexity is O (n ). Example: For example, the input array is {1,-2, 3, 10,-4, 7, 2,-5}, and the maximum sub-array is {3,

Getting started with C Programming in Unix/Linux (31) how to beat enterprise interviews with mathematical functions and how to get started with linuxAdvanced Programming in unix environments is different from that in linux C programming. You can think of the former as a unix/linux system-related learning, such as api or something, as well as some theories and concepts.The latter only learns the C language, the grammar, and the data structure.The latt

Reactive C ++: Clause 31: minimizes the compilation dependency between files. Reactive dependency If you are modifying the program, you only modify the implementation of a class interface and modify the private part. After that, you will find that many files have been re-compiled. This problem occurs in the absence of "Separating interfaces from implementations ". The definition of Class not only describes the class interface in detail, but also i

. Adopt appropriate methodsAt the beginning, we have already said that the management area allocation page cannot be repaired or restored, so we have to restore the entire database, so we need to check the backup, especially when the transaction log is backed up and then restored. If there is no backup, you need to import the data to a new database. If you can manually use a hexadecimal editor to fix it (not Nb or ds), You 'd better copy it first for this operation.

In actual use, the difficulty lies in how to accurately abstract conditions. For example, if the user name and password are correct during program logon, the system is displayed. Otherwise, a p

A tricky question. An array. Find the subscript of the first Nums [I] This is also very easy. We only need to find the first element later than Nums [I] and exchange it with Nums [I] (This one must be the smallest one ), then I + 1 ~ Just reverse the n-1 sequence. Of course, the first element greater than Nums [I] can be optimized using binary optimization, but in any case, the overall time complexity is O (n ). class Solution {public: void nextPermutation(vector Leetcode

to any negative number, this behavior will also happen. If you declare I as a char, you will not be able to get an infinite loop, because Char is unsigned, so expanding the original type conversion before the shift will not execute symbol extension. In short, do not use the composite value assignment operator on a variable of the short, byte, or char type. This expression executes mixed arithmetic operations, which can easily cause confusion. Even worse, their execution will implicitly implemen
