Given a vector of integers, remove the elements that have appeared only once. The output elements should be in exact order as the input except the single elements being removed.
Example:
Input: vec = [2 2 1 2 3 4 1 2]; Output: [2 2 1 2 1 2];
Loops are not allowed.
Since matlab has so many different ways of representing the empty set, could you test for emptiness using isempty(...) rather than isequal([], ...) ?
Test suit # 4 should not compare out = [] with output of the function but rather isempty(out) !!!
function A=removeSingle(A)
[n, bin] = histc(A, unique(A));
multiple = find(n ==1);
index = find(ismember(bin, multiple));
A(index)=[];
end
failed for 4 test suit help me
>> A = 1;A(1)=[];size(A)
ans =
1 0
>> size([])
ans =
0 0
