Largest Unique Number in Python - Suppose we have a list of numbers, we have to return the number whose occurrence is 1, if no such element is present, then return -1. So if the list is like [5,2,3,6,5,2,9,6,3], then the output will be 9.To solve this, w

TheNumPy unique function in Pythonis used to find the unique elements of an array. It returns the sorted unique elements of an array, providing options to return indices, the number of times each unique item appears, and a reversed index. MY LATEST VIDEOS Example:Let’s take an array and ...
Unique Number of Occurrences in Python - Suppose we have an array, and we need to check whether each element has a unique number of occurrences. If no such element exists, we return false; otherwise, we return true. For example, given the array [1, 1, 2,

Problem Statement:Consider that you have been given a list in Python. How will you count the number of unique values in the list? Example:Let’s visualize the problem with the help of an example: Given: li = [‘a’, ‘a’, ‘b’, ‘c’, ‘b’, ‘d’, ‘d’, ‘a’] ...
Returns the sorted unique elements of an array. There are three optional outputs in addition to the unique elements: the indices of the input array that give the unique values, the indices of the unique array that reconstruct the input array, and the number of times each unique value comes ...
