Topic:There is n bulbs that is initially off. You first turn the bulbs. Then, you turn off every second bulb. On the third round, you toggle every third bulb (turning on if it's off or turning off if it's on). For then-th round, you are only toggle the last bulb.

So you should return 1, because there are only one bulb are on.Answer:We know that whenever a light bulb changes state, that is

is, an even number of switch, so that the off or off,on or on, that is, to remain unchanged, in addition to a situation, is 3x3 this, if the sqrt (interval) is an integer, Indicates that there is an odd number of switch, the state changes will occur, then we can now consider this problem is very simple, because at the beginning all the bulbs are extinguished, so we just need to look for 1. Less than n,2. And sqrt is the number of integers. The answer is obviously sqrt (n) Code: class Soluti

, the 2594 drops to its pulse-by-pulse limited-protection mode, followed by a reduction in clock frequency if the Overload is severe. This design example uses Through-hole components, because LOW-ESR capacitors and inductors in through-hole form is INEXPE Nsive and easy to find. Worst-case line and load conditions cause Q1 and D1 to dissipate 3W each, so you must choose a heat-sink size to keep the temperature rise within acceptable limits. A Heat-sink rating of 6 to 7°C/W can accommodate

Android learning-grid view and image switcher) The GridView is used to display multiple components by row and column distribution on the interface. The GridView and ListView have the same parent class: AbsListView. The difference between the GridView and ListView is that the ListView is distributed only in one direction, and the GridView is distributed in two directions. Therefore, when using the GridView, numColumns is generally specified to be gre

When an event on an element is triggered, for example, if you click a button, the same event will be triggered among all the ancestor elements of that element. 1. event TargetNow, the variable event in the event handler stores the event object. The event.tar get attribute stores the target element of the event. This attribute is specified in the dom api but is not implemented by all browsers. JQuery makes necessary extensions to this event object so that this attribute can be used in any browser

This attribute is specified in the dom api but is not implemented by all browsers. JQuery makes necessary extensions to this event object so that this attribute can be used in any browser. Through .tar get, you can determine the elements in the DOM that receive the event first (that is, the actually clicked element ). Furthermore, we know that t

To edge his way along the crowded paths of life, warning all human sympathy to keep its distance, was what the knowing ones call "nuts" to Scrooge.

JQuery implements login and registry ticket switching in the pop-up window This article recommends a jQuery special effect for switching between logon and registry tickets in the pop-up window. Applicable browsers: IE8 +, FireFox, Chrome, Safari, and Opera. It is very convenient and practical. If you need it, you can refer to it. When you click the "Log on" or "register" button on the page, a modal window is displayed, which is a pop-up layer. We can easily switch between logon and registry tick

This article introduces JQuery to let the sliding door slide up. First look at a I streamlined out of the DEMO.
