I got these questions in a Hackerrank assessment for a CA based company. Wasn\'t practicing leetcode at the time, so failed both of them.\n\n<details> \n  <summary>Question 1</summary>\n\n![image](https://assets.leetcode.com/users/michaelhly/image_1566600342.png)\n</details>\n\n<details> \n  <summary>Question 2</summary>\n\n![image](https://assets.leetcode.com/users/michaelhly/image_1566600610.png)\n![image](https://assets.leetcode.com/users/michaelhly/image_1566600632.png)\n</details>\n\nFirst question seems like standard DP, something I should\'ve been able to do. The second one seems like a graph problem? I still don\'t understand, would love some help solving it.
