3. Using NumPy to Find Most Common Elements in Large Numerical Arrays For numerical data,numpyprovides efficient array-based operations. Thenumpy.unique()can be used to get unique elements along with their counts. Find Most Frequent 2 Elements importnumpyasnp sequence=np.array([1,2,3,4,1,2...
The following function will return the kthlargest element in a list by sorting the list in descending order and returning the kthelement. This approach has a time complexity of O(n log n) due to the sorting operation. Additionally, sorting a list with a large number of unique elements might...
2) Using for Loop Theforloop is used to iterate the sequence of elements (list, tuple, dictionary, etc.). Here, we can also define the range in for loop its syntax is different from the for loop of c programming language but can say that it is like for each loop. Syntax: for vari...
class Solution: def findDifferentBinaryString(self, nums: List[str]) -> str: nums_set = set(nums) while True: s = "" for _ in range(len(nums)): s += random.choice(["0", "1"…
Here, we have a list of tuples and we need to find all the tuples from the list with all positive elements in the tuple.
This code computes a list of unique elements in the source order:seen = set() uniq = [] for x in a: if x not in seen: uniq.append(x) seen.add(x) or, more concisely:seen = set() uniq = [x for x in a if x not in seen and not seen.add(x)] ...
You could scan the list from start to end, while maintaining amapof encountered pairs to their first position. Whenever you process a pair, you check to see if you've encountered it before. If that's the case, both the first encounter's index in b and the current encounter's index mus...

array2 = [10, 30, 40, 50, 70]: Creates a Python list with elements 10, 30, 40, 50, and 70. print(np.union1d(array1, array2)): The np.union1d function returns the sorted union of the two input arrays, which consists of all unique elements from both ‘array1’ and ‘array2’...
