Find Largest element in an array
Detailed guide and Python implementation for the 'Find Largest element in an array' problem.
Problem Statement
Write a function find_largest(arr) that takes a list of integers arr and returns the largest element. Iterate through the array and track the maximum value seen so far.
- •1 <= len(arr) <= 10^5
- •-10^9 <= arr[i] <= 10^9
Examples
arr = [3, 7, 2, 8, 1]
8
Comparing all elements: 3, 7, 2, 8, 1. The maximum is 8.
arr = [-5, -2, -8, -1]
-1
Among negative numbers, -1 is the largest.
arr = [100]
100
Only one element, so it is the largest.
