3. Find Largest of Three Integers

Easy

Problem Description

Given three integers AA, BB, and CC, find and print the largest value among them without using built-in array sorting.

Input Format

A single line containing three space-separated integers AA, BB, and CC.

Output Format

Print the single maximum integer value.

Example 1:
Input:
5 12 9
Output:
12
Explanation: Comparing 5, 12, and 9: 12 is greater than both 5 and 9.
Example 2:
Input:
-3 -8 -1
Output:
-1
Explanation: Among negative integers, -1 is closest to zero and thus the largest.
Example 3:
Input:
7 7 7
Output:
7
Explanation: All three integers are equal, so the maximum is 7.
Constraints:
  • -10^9 <= A, B, C <= 10^9
  • Time complexity target: O(1)
  • Auxiliary space target: O(1)
Follow up:How would you scale this to find the maximum of N streaming numbers with O(1) memory?
