So my code is supposed to work so for an input array, findSortedMatches sorts the array and looks for rows that didn’t move. It returns the number of rows that didn’t move (matches) and an array of the rows that didn’t move (matched rows).
Code
function [matches, matched_rows] = findSortedMatches(score)
score = [N,2];
matches = 0;
matched_rows = [];
[~, sorted] = sortdata(score);
next_unsorted = make_nextRow(score,1);
next_sorted = make_nextRow(sortdata,1);
for i = 1:size(score,2)
unsorted = next_unsorted;
if all(unsorted==next_sorted)
next_sorted() matches unsorted
matches = matches + 1;
matched_rows = [matched_rows; unsorted];
end
end
end
function [data_sortbyscore, bestscore_id] = sortdata( score )
[~, idx] = sort(score(:, 2));
data_sortbyscore = score(idx, :);
bestscore_id = data_sortbyscore(end, 1);
end
Test Case and Expected Answers
>> scores = [20,90;13,56;3,67;10,78;2,54];
>> [num_matches, row_matches] = findSortedMatches(scores)
num_matches =
3
row_matches =
13 56
3 67
10 78
>>
>>
>> array = [2 34; 5 67];
>> [num_matches, matched_rows]=findSortedMatches(array)
num_matches =
matched_rows =
2 34
5 67
>> array = [5 67; 2 34];
>> [num_matches, matched_rows]=findSortedMatches(array)
num_matches =
matched_rows =
