यह देखते हुए कि बाइनरी मैट्रिक्स में 0 और 1 है, हमारा काम डुप्लिकेट पंक्तियों को ढूंढना और उसे प्रिंट करना है।
पायथन काउंटर () विधि प्रदान करता है जिसका उपयोग यहां किया जाता है।
उदाहरण
Input: 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 Output: (1, 1, 1, 1) (0, 0, 0, 0)
एल्गोरिदम
Step 1: Create a binary matrix, only 0 and 1 elements are present. Step 2: Which will have rows as key and it’s frequency as value. Lists are mutable so first, we will cast each row (list) into a tuple. Step 3: Create a dictionary using the counter method. Step 4: Now traverse the dictionary completely. Step 5: Print all rows which have frequency greater than 1.
