Implement a function in Java to find the largest and smallest elements in an array of integers, and return them in a pair. The function should have a time complexity of O(n) and a space complexity of 0(1).

The sieve of Eratosthenes is a way of computing all the prime numbers below a certain number. (A prime number is a number that is only divisible by itself and 1). Implement this algorithm: Implement a function cross_out_multiples that takes as arguments a list of boolean values (true/false) called is_prime and a number n. The function sets the boolean values at all multiples of n (2*n, 3*n, 4*n ...) that are in the list to false. Implement a function sieve(n) which gives back a list of all primes below n. Put your code in sieve.py This program is tested via unit tests.

Write a java program to print the number from 1 to 100 without using loop, recursion, bitset.Think about arrays and do this with array in O(1) time complexity

LeetCode Given an array of strings words representing an English Dictionary, return the longest word in words that can be built one character at a time by other words in words. If there is more than one possible answer, return the longest word with the smallest lexicographical order. If there is no answer, return the empty string. Example 1: Input: words = ["w","wo","wor","worl","wo Output: "world" Explanation: The word "world" can be buil Example 2: Input: words = ["a", "banana", "app","appl" Output: "apple" Explanation: Both "apply" and "apple" can Constraints: • 1 <= words.length <= 1000 • 1 <= words [i]. length <= 30 words [1] consists of lowercase English letters.

Solution in Java Create a function that takes an array of increasing letters and return the missing letter. Examples missing Letter (["a", "b", "c", "e", "f", "g"]) → "d" missing Letter (["O", "Q", "R", "S"]) → "P"
