Given a binary matrix, print all unique rows of the given matrix. Order of row printing doesn’t matter.
Input: mat = [[0, 1, 0, 0, 1], [1, 0, 1, 1, 0], [0, 1, 0, 0, 1], [1, 1, 1, 0, 0]] Output: (1, 1, 1, 0, 0) (0, 1, 0, 0, 1) (1, 0, 1, 1, 0)
We have existing solution for this problem please refer link. We can solve this problem in python quickly using Set data structure. Approach is very simple.
- We are given list of boolean values list, put all rows (list) in set because set contains unique values.
- Since list is an unhashable type for set because it is mutable that’s why first we convert each row (list) into tuple then we put all tuple in set.
- Resultant set will contain only unique valued tuples (row).
(1, 1, 1, 0, 0) (0, 1, 0, 0, 1) (1, 0, 1, 1, 0)
