问题 Can we place a small view over another large view? For example, I have a VideoView which is playing a file in the background. Over this, somewhere in the middle/corner, I want to place another ImageView. But in Linear/Relative Layout, views can be placed only one after another or relative to each other, and AbsoluteLayout is advised against. So what do I do? 回答1: FrameLayouts let you pile each view on top of the one below. This can also be achieved with a RelativeLayout . 回答2: The FrameLayout

Please look into this inexplicable behavior and output of memcpy() for overlapping memory blocks

After reading the following about memcpy() , I proceeded to read about memmove() : To avoid overflows, the size of the arrays pointed by both the destination and source parameters, shall be at least num bytes, and should not overlap (for overlapping memory blocks, memmove is a safer approach). (LINK) And after checking the program used to illustrate the working of memmove() I decided to tweak it by using memcpy() instead to see how different is the output.To my surprise,they are the same even if it's a case of overlapping memory blocks.Here is the program and the output,and I have proceeded to

Text wrapping issue in generated pdf file

I have an issue related to wrapping of text in pdf format. For all the formats like xls,rtf, and pptx the report works fine,however in pdf some text gets wrapped i.e. some letters of the text especially the last few letters gets printed in the next line. I have tried almost all the options in the properties for that text. The only way I could reduce the effect was by changing the pdf font name to times roman for those text. However even this does not work in some case. The snippet contains problem TextField : <textField isBlankWhenNull="true"> <reportElement positionType="Float" x="560" y="0"

问题 Can anyone please suggest me algorithm for this. You are given starting and the ending points of N segments over the x-axis. How many of these segments can be touched, even on their edges, by exactly two lines perpendicular to them? Sample Input : 3 5 2 3 1 3 1 5 3 4 4 5 5 1 2 1 3 2 3 1 4 1 5 3 1 2 3 4 5 6 Sample Output : Case 1: 5 Case 2: 5 Case 3: 2 Explanation : Case 1: We will draw two lines (parallel to Y-axis) crossing X-axis at point 2 and 4. These two lines will touch all the five

Merging intervals in one pass in SQL

空扰寡人 提交于 2019-11-28 00:15:21
Let's say I have a table with two columns: start and end , both integers, and the table is ordered by the first, then second column. Each row represents an interval. What I need is the table of merged intervals: all overlapping or adjacent intervals gobbled up into one. It can be constructed with a JOIN query, but that is quadratic in the number of rows, which is 4 million rows in my case (I decided to compose this question because the query is still running). It can also be done in a single pass, by running through each row and keeping track of the maximum end time - but how to do that, or
