How to Find the Position of an Element in a List Problem Description Given a sequence containing n integers, determine the position of integer a in the sequence. Input Format The first line contains an integer n.The second line contains n non-negative integers, which are the given sequence. ...
Example 1: Get the Position of an Element Using the “index()” Method from the Python List The “index()” method integrated into Python provides a basic and straightforward technique to discover the location of an element in a list. If the element exists, it delivers the index of its i...

[Leetcode][python]Find First and Last Position of Element in Sorted Array/在排序数组中查找元素的第一个和最后一个位置 题目大意 给定一个按照升序排列的整数数组 nums,和一个目标值 target。找出给定目标值在数组中的开始位置和结束位置。 你的算法时间复杂度必须是 O(log n) 级别。
list_example = [1, 2, 2, 3, 3, 3] print(set(list_example)) # {1, 2, 3} str_example = "banana" print(set(str_example)) # {'a', 'b', 'n'} dict() - 创建字典 dict() 函数可以从键值对序列创建字典。 list_of_tuples = [("name", "Alice"), ("age", 25)] print(dict...
Out of 7 integers, the minimum element is 12 and its index position is 0. 3. Using for loop & index() to Get Min Index Here, we will iterate all elements in the list and compare whether the element is minimum to the current iterating value, If it is minimum, we will store this ...
34. Find First and Last Position of Element in Sorted Array Given an array of integers nums sorted in ascending order, find the starting and ending position of a given target value. Your algorithm's runtime complexity must be in the order of O(log n). ...
