The project is using SonarCloud static code analysis. The latest results are showing that it has found several blocker and critical severity code smells. In this task those are fixed or marked as false positives. To mark false positives, SuppressWarnings annotation should be used in code as explained in the linked documentation.

• We have BFS and DFS images in both Breadth First Traversal and Depth First Traversal. We should have illustrations in the respective sections.

MutableClassToInstanceMap

I think it permits null values but not keys. Eventually we should have nullness annotations that make the clear, but even then, it's nice to document up front, as we do for most other types.

Perhaps the ClassToInstanceMap interface should also be clearer that null keys are forbidden and null values might or might not be.

给定两个由小写字母构成的字符串 A 和 B ，只要我们可以通过交换 A 中的两个字母得到与 B 相等的结果，就返回 true ；否则返回 false 。

示例 1：

输入： A = "ab", B = "ba"
输出： true
示例 2：

输入： A = "ab", B = "ab"
输出： false
示例 3:

输入： A = "aa", B = "aa"
输出： true
示例 4：

输入： A = "aaaaaaabc", B = "aaaaaaacb"
输出： true
示例 5：

输入： A = "", B = "aa"
输出： false
 

提示：

0 <= A.length <= 20000
0 <= B.length <= 20000
A 和 B 仅由小写字母构成。

There should be a README file for each type of design pattern which should include the following points-

• Description of the design pattern
• Common use cases of that design pattern
• Explanation of the code

Many users confuse about no class, no method, expression error.

Arthas should add a verbose/debug option, to print the command arguments and the debug info in command execution.

What's the ETA for updating the massively outdated documentation?

Please update all documents that are related building CNTK from source with latest CUDA dependencies that are indicated in CNTK.Common.props and CNTK.Cpp.props.
I tried to build from source, but it's a futile effort.

[REQUIRED] Use case description

Given our not super strict security requirements, we're trying to understand if allowing downloaded .exo files to be in the external storage system would be reasonable.

• It's clear it's not straightforward to play them outside the app where they were downloaded, but it'd be nice to understand in details what it takes to be able to do that, so it's easy to
