Sometimes when we are writing JS, we need to trigger events without returning values, so we might need to write this.I've seen several posts on Note: The following code is not fully tested, but the scenario that each method may appear is basically explained.When making a page, if you want to do a link click Do not do anything, or in response to click to complete other things, you can set its properties href = "#", but this will have a problem, that is, when the page has a scroll bar, click will

. Numberpicker.onscrolllistener: The scroll state used to listen for the control. The following three states are mainly included: Scroll_state_touch_scroll: The user presses down and then slides. Scroll_state_fling: Equivalent to the subsequent slide operation of the Scroll_state_touch_scroll. Scroll_state_idle:numberpicker is not scrolling. Numberpicker.formatter: Used to format the display of value in the component, such as

0-1 backpack problem: A thief in the theft of a shop, found that there are n items, the value of the article I item VI, heavy WI-lb, where VI and WI are integers. He hopes to take away the goods the more valuable the better, but his backpack can only be loaded W-pounds of Things, W is an integer. What kind of things should I take? This problem is called the 0-1 backpack, because each item or is taken away,

Given a group of items, each item has its own weight and value. within the defined total weight, how can we choose to make the total price of the item the highest. Solution: value density PI/wi (PI indicates the value of the item I, and WI indicates the weight of the item I) greedy algorithm. This selection criterion is: select the item with the highest PI/wi value from the remaining item. 0/1 the knapsack problem is an NP complex problem (NP comple

0-1 integer Programming and implicit enumeration-feeling the charm of pruningInteger Planning is a special case of linear programming, that is, when the constraint is a variable integer, the linear programming becomes the integer plan. If all variables are required to be integers, it is a pure integer plan ; If some of the variables are allowed to be integers, it is called mixed integer planning . the 0-1 i

Given any permutation of the numbers {0, 1, 2,..., N-1}, it's easy-to-sort them in increasing order. What if swaps (0, *) are the only operation and that's allowed to use? For example, to sort {4, 0, 2, 1, 3} We'll apply the swap operations in the following: Swap (0, 1) = = {4, 1, 2,

I have recently read several posts on Note: The following code is not fully tested, but the situation that each method may appear is largely explained.When making a page, if you want to do a link click Do not do anything, or respond to click and complete other things, you can set its properties href = "#", however, this will have a problem, that is, when the page has a scroll bar, click will return to the top of the page, the user experience is not good. Currently, there are several solutions:

We often see 0 euro resistance in the circuit. For new users, it is often confusing: since it is a 0 euro resistance, it is a wire, why should we install it? Is there such a resistance market available? In fact, 0 euro resistance is quite useful. The following functions are available:① Used as jumper. This is both beautiful and easy to install.② In digital and an
