11\. Container With Most Water
2+
3+
Medium
4+
5+
Given `n` non-negative integers `a1, a2, ..., an` , where each represents a point at coordinate `(i, ai)`. `n` vertical lines are drawn such that the two endpoints of the line `i` is at `(i, ai)` and `(i, 0)`. Find two lines, which, together with the x-axis forms a container, such that the container contains the most water.
6+
7+
**Notice** that you may not slant the container.
8+
9+
**Example 1:**

![](https://s3-lc-upload.s3.amazonaws.com/uploads/2018/07/17/question_11.jpg)
12+
13+
**Input:** height = \[1,8,6,2,5,4,8,3,7\]
14+
15+
**Output:** 49
16+
17+
**Explanation:** The above vertical lines are represented by array \[1,8,6,2,5,4,8,3,7\]. In this case, the max area of water (blue section) the container can contain is 49.
18+
19+
**Example 2:**
20+
21+
**Input:** height = \[1,1\]
22+
23+
**Output:** 1
24+
25+
**Example 3:**
26+
27+
**Input:** height = \[4,3,2,1,4\]
28+
29+
**Output:** 16
30+
31+
**Example 4:**
32+
33+
**Input:** height = \[1,2,1\]
34+
35+
**Output:** 2
36+
37+
**Constraints:**
38+
39+
* `n == height.length`
40+
* `2 <= n <= 105`
41+
* `0 <= height[i] <= 104`

12\. Integer to Roman
2+
3+
Medium
4+
5+
Roman numerals are represented by seven different symbols: `I`, `V`, `X`, `L`, `C`, `D` and `M`.
6+
7+
Symbol Value
8+
I 1
9+
V 5
10+
X 10
11+
L 50
12+
C 100
13+
D 500
14+
M 1000
15+
16+
For example, `2` is written as `II` in Roman numeral, just two one's added together. `12` is written as `XII`, which is simply `X + II`. The number `27` is written as `XXVII`, which is `XX + V + II`.
17+
18+
Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not `IIII`. Instead, the number four is written as `IV`. Because the one is before the five we subtract it making four. The same principle applies to the number nine, which is written as `IX`. There are six instances where subtraction is used:
19+
20+
* `I` can be placed before `V` (5) and `X` (10) to make 4 and 9.
21+
* `X` can be placed before `L` (50) and `C` (100) to make 40 and 90.
22+
* `C` can be placed before `D` (500) and `M` (1000) to make 400 and 900.
23+
24+
Given an integer, convert it to a roman numeral.
25+
26+
**Example 1:**
27+
28+
**Input:** num = 3
29+
30+
**Output:** "III"
31+
32+
**Example 2:**
33+
34+
**Input:** num = 4
35+
36+
**Output:** "IV"
37+
38+
**Example 3:**
39+
40+
**Input:** num = 9
41+
42+
**Output:** "IX"
43+
44+
**Example 4:**
45+
46+
**Input:** num = 58
47+
48+
**Output:** "LVIII"
49+
50+
**Explanation:** L = 50, V = 5, III = 3.
51+
52+
**Example 5:**
53+
54+
**Input:** num = 1994
55+
56+
**Output:** "MCMXCIV"
57+
58+
**Explanation:** M = 1000, CM = 900, XC = 90 and IV = 4.
59+
60+
**Constraints:**
61+
62+
* `1 <= num <= 3999`

59+
60+
**Constraints:**
61+
62+
* `1 <= s.length <= 15`
63+
* `s` contains only the characters `('I', 'V', 'X', 'L', 'C', 'D', 'M')`.
64+
* It is **guaranteed** that `s` is a valid roman numeral in the range `[1, 3999]`.
