Other Programming Languages If you have a coding issue to discuss about another language that really isn't provided for in any other forum here (not ASP.NET C#, C++, VB, PHP, JavaScript, Python, Java, Perl, Applescript, XML or any of the other forum topics we have), post it here. Enough discussion on a language we don't have covered could prompt a new forum.

Default How to get least value numbers in a sorted array?


   I had a doubt that if we have an sorted array with some numbers like 45,54,65,34,34,23,78. How can we get the least umbers in this arrray?
Please reply me as soon as possible.

Ashok, it will depend on your language very much, but in principle, you would code for a 'bubble sort', which means you look at each elememt in the array in turn and compare it to the other elements. Storing the lower number in a variable on each comparison, until eventually the smallest number is stored in the variable. Post again with more detail, I write in Visual Basic.liamfitz.

in javascript/perl/php slight difference in declaration of variables but i will do it in js. Per suggested previously.

var lowest_num=0;
for(var i=0;i<array_name.length;i++){
 if(array_name.length != i){ // no need to look at last
  var temp_holder = array_name[i];
  var temp_holder2 = arrau_name[i+1] // look one ahead
  if(temp_holder < temp_holder2){

should be fairly close, if not working

now if you wanna build a numerically sorted array, i suggest you look at "push / pop" method

Most languages have built in sorting, which works well in the majority of cases - you should use these. If keeping the information in a sorted order is important you may want to consider using a data structure other than an array.

Anyhow, here's a couple of snippets that find the lowest number in an array.

Here's a perl version:
my @unsorted = (34, 69, 12, 67, 21, 9, 78, 478327);
my @sorted = sort {$a <=> $b} @unsorted;
print "$sorted[0]\n";
Here's a ruby version:
arr=[34, 69, 12, 67, 21, 9, 78, 478327]
p arr.sort.first

Don't Stand on your head - you'll get footprints in your hair
