I have a doubt between the subsequence and subset of the array. Suppose I have an array:
nums = [1,2,3]
output = [[],[1],[2],[1,2],[3],[1,3],[2,3],[1,2,3]]
Whether output contains subsequence or subset of the nums ?
Subsequence means maintaing the relative order but may/may not be contigous. And subset means any combination of elements.
So I think we can say output conatins both subsequence and subset of nums ?
Can anyone help me in clarifying it?
