How to find triplets in an array python
Given a list of integers, write a Python program to find all triplets that sum up to given integer ‘k’. Show Examples: Input : [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], k = 10 Output : [(1, 5, 4), (1, 6, 3), (1, 7, 2), (2, 5, 3)] Input : [12, 3, 6, 1, 6, 9], k = 24 Output : [(12, 6, 6), (12, 9, 3)] Approach #1 : Naive (Using set)
Output: [(1, 5, 4), (1, 6, 3), (1, 7, 2), (2, 5, 3)]
Output: [(1, 2, 7), (1, 3, 6), (1, 4, 5), (2, 3, 5)] How do you find triplets in an array Python?Triplets can be found using the hashing technique.. Traverse the array from i = 0 to n - 2.. Create an empty hash table.. Traverse from j = i+ 1 to n -1.. sum = arr[i] + arr[j]. if (-sum) is present in the hash table,. then print arr[i], arr[j] and -sum as triplets.. else, insert arr[j] in the hash table and proceed.. How do you find the number of triplets in an array?Check if arr[i]+arr[j]==arr[k] or arr[i]+arr[k]==arr[j] or arr[k]+arr[j]==arr[i] If true then increment count. At the end of all loops count will have a total number of triplets that meet the condition. Return the count as result.
How do you get triplets from a list in Python?Given a list of integers, write a Python program to find all triplets that sum up to given integer 'k'. In this approach, we use two for loops. The first loop sets first element, another to check whether other two elements including first sums up to k or not. This approach takes O(n2) time complexity.
How do you print all triplets in array?Given an array of distinct elements.. Take three pointers i, j, k.. Initialize i with zero and start a nested loop for i.. Initialize j with (i+1) and start a nested loop for j.. Initialize k with (j+1) and start a loop for k.. If Target == arr[i] + arr[j] + arr[k] break the loop and print values of arr[i], arr[j], arr[k].. |
