perl - How can I compare two arrays with alphanumeric elements? -


i have 2 arrays want compare 

 @array1 = ( aaa, bbb, aaabbb, aaa23bbb, ddd555, 430hd9789);   @array2 = ( 34322hh2, jjfjr78, uuu7shv, ddd555, hjkdjroo);

i have compare these 2 arrays , find duplicate , it.

conditions:

  1. length of each element in array can different. there no such fixed pattern.

  2. elements can numeric i.e. 334343, or char i.e. "somewordexample", or can alphanumeric i.e. wewe83493

  3. there can more such elements in array.

now know following comparison operators == , eq:

== comparing numbers

eq string comparison

how can compare alphanumeric values?

this code far

for (my $i = 0 ; $i <= $#array1 ; $i++ ) {   (my $j = 0 ; $j <= $#array2 ; $j++ ) {     if ( $array1[$i] == $arra2[$j] ) {       print "duplicate";     }   } }

you manner indolent, , seem looking quick fix without caring whether understand solution. posts on stack overflow people other originator may have similar problem.

you should read perlfaq4. specifically:

  • perldoc -q intersection - "how compute difference of 2 arrays? how compute intersection of 2 arrays?"

  • perldoc -q contained - "how can tell whether element contained in list or array?"

  • perldoc -q duplicate - "how can remove duplicate elements list or array?"

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
