How can I sort an array of strings, if there is an array, where sorting is followed in order, as I need. In my case it is:

  1. T-90
  2. T-100
  3. T-110
  4. T-120
  5. Tv
  6. No analysis
  7. Not standard
  8. Defective

And I have my own array, which I need to sort by the list above. How to do it?

    It is possible for more details with an example of what we have and what to get at the output) bring a small piece pliz - Ale_x
  • I correctly understand that: - You have a certain list of strings / arrays / tuples / objects that you want to sort. - Objects in your list as one of their fields / elements contain a string. - This line can take one of 8 values ​​described in the question. - You want to sort your list by this string value, in accordance with the priorities of possible values ​​(first T-90, then T-100, and so on). - Nofate

Very sketchy. Get the function of comparing two elements A and B, which would be:

  1. would look for position A in the reference array (a)
  2. would search for position B in the reference array (b)
  3. would return (ab), that is,> 0 if A is "greater than" B, 0 if A "is equal to" B, <0 if A is "less than" B

Well, continue to use this feature as an aid to QuickSort, for example. With cases where A or B are not in the reference array, or there is a partial match, or something else, figure it out yourself :)


    I don't even know how this can sort

    Тв Без анализа Не стандартная Брако 

    First TV, then B, then H, then again B ...

      The first thing that comes to mind: if the data is taken from the database, then enter additional fields for sorting. In any case, there must be a sign by which it is sorted.
