markdown - Using an image map in a github readme.md file -


is there option include image in readme.md file, has usemap attribute?

pure html be

<img src="myimage.png" usemap="#mymap"/> <map name="mymap">   <area coords="1,1,40,40" href="mylink.html"/> </map>

i can't work multiple reasons

  • usemap retained attribute map-block removed. not surprising map-tag not on html whitelist, if not mistaken.
  • an image map cannot inside anchor tag github markdown renders a-tag pointing raw file location , img-tag inside.

i don't see option, you?

okay, sort of solution , advice use css, not img's usemap attribute.

the best answer came using github pages - these static web pages hosted github , therefore can want there.

https://help.github.com/articles/creating-a-github-pages-site-with-the-jekyll-theme-chooser/

this creates new branch gh-pages , html files used. convenient not have checkin master branch changes.

the endresult not image map inside readme.md file, there have added link github-pages index.html using imagemap. imagemap points various github resources. not inline readme.md 1 click away.

second finding: don't use image maps css instead. imagemap coords depend on width of image rendered browser, not on width of image itself. in github standard use max-width style property, image gets scaled down - , coords of imagemap not.

much better use css - see "responsive image maps" - , percent values.

<p style="position: relative;">   <img ....>   <a style="position: absolute; top: 10%; left: 10%; width: 30%; height: 15%" href=....></a> </p>

as both, image , anchor tag inside block element of position relative , anchor tag of position absolute, anchor position scaled image.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
