Container With Most Water

Input

Output

Sample case — your program reads stdin and prints to stdout.

Given n non-negative integers representing heights of vertical lines at positions 0 to n-1, find two lines that together with the x-axis form a container that holds the most water.

Use two pointers from both ends, moving the shorter one inward.

Area = min(height[left], height[right]) * (right - left)

Example: [1,8,6,2,5,4,8,3,7] → Max area = 49 (between positions 1 and 8)

Input format Line 1: n. Line 2: n space-separated integers (heights).

Output format The maximum area.

Constraints 2 ≤ n ≤ 10⁵, 0 ≤ height[i] ≤ 10⁴

Every problem you solve becomes a story you can tell in an interview.

Solving under pressure trains the muscle that's most tested in onsite rounds.
Explaining your approach out loud matters more than reaching the optimal solution.
Consistency wins: 1 challenge daily > 10 challenges on one Saturday a month.

Pro tip:After solving, write 2 lines on what you learned — that's what you'll remember in the interview.
