javascript - Confuse in <meter> tag -


can me understand difference between 2 meter , why colour difference between them although have same value ??

<meter low="69" high="80" max="100" value="84">a</meter><span>mdn example</span> <br>    <meter low="30" high="80" max="100" value="84">b</meter>

that because of different low , high values.

now meter tag forms 3 regions:

one min(0) low, low high , third high max(100).

default value of optimum 50. can set whatever value want. in ever region optimum lies colored green. neighbour region colored yellow , farthest colored red.

in first example, default optimum value 50. if make low=60 , high=80, between 0 60 green, between 60 80 yellow , 80 100 red.

in second example, have set optimum=70, keeping low , high value same. between 0 60 yellow, between 60 80 green , 80 100 yellow.

<p>first exmple</p>  <meter low="60" high="80" max="100" value="34">a</meter><br/>  <meter low="60" high="80" max="100" value="65">b</meter><br/>  <meter low="60" high="80" max="100" value="84">c</meter><br/>  <p>second exmple</p>  <meter low="60" high="80" optimum="70" max="100" value="34">a</meter><br/>  <meter low="60" high="80" optimum="70" max="100" value="65">b</meter><br/>  <meter low="60" high="80" optimum="70" max="100" value="84">c</meter><br/>

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...
