Given a nested list of integers, return the sum of all integers in the list weighted by their depth. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Different from the previous question where weight…

B. Pasha and PhonePasha has recently bought a new phone jPager and started adding his friends' phone numbers there. Each phone number consists of exactly n digits. Also Pasha has a number k and two sequences of length n / k (n is divisible by k) a1, …

相信大家在日常开发中一定使用过weight这个属性,它的作用一个是权重,另一个就是渲染优先级,但是你真的能很6的使用它嘛?如果不是,那么请继续往下看!!! 我们知道,当weight起到不同作用的时候,weight属性的值可以影响控件的效果.但是具体的影响是怎么样的哪? 当起权重作用的时候,weight属性值越大,占据的空间越大.(要求weight属性必须和0dp一起使用) 当起渲染优先级作用的时候,weight属性值越大,越后渲染. 其实,所谓占据空间大小是根据下面这个公式算出来的: 实际宽(高…

android:layout_weight是一个经常会用到的属性,它只在LinearLayout中生效,下面我们就来看一下: 当我们把组件宽度设置都为”match_parent”时: <Button android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="3" android:text="按钮1&…
