You are given an array of integers nums representing coin denominations and an integer amount representing a total amount of money. You need to write a function to compute the fewest number of coins that you need to make up that amount. If that amount of money cannot be made up by any combination of the coins, return -1. Example 1: nums = [1, 2, 5] amount = 11 Answer: 3 (11 = 5 + 5 + 1) Example 2: nums = [2] amount = 3 Answer: -1 (You cannot make up the amount 3 with only coins of denomination 2) Constraints: 1 <= nums.length <= 12 1 <= nums[i] <= 1000 0 <= amount <= 10000 Clarifications: Are the coin denominations always positive integers? Is there a limit to the number of times each coin can be used? If the amount is 0, what should the function return?

Let's say you've developed a new feature for a high-traffic e-commerce website. The feature allows users to save items to a wishlist. You've tested it thoroughly in your development environment, and it seems to be working perfectly. Now, you need to deploy this feature to the production environment, where thousands of users will interact with it simultaneously. Describe the steps you would take to safely and successfully deploy this feature to production.** What are the key considerations you'd keep in mind during each stage of the deployment process?** How would you monitor the feature's performance and identify potential issues after deployment?** What rollback strategies would you have in place if something goes wrong during or after the deployment?** For instance, would you use a blue-green deployment, canary release, or some other strategy? How would you handle database migrations, caching, and potential security vulnerabilities? What metrics would you track to ensure the feature is performing as expected and not negatively impacting the overall site performance? What tools would you use for monitoring and alerting? Finally, how would you communicate the deployment progress and any issues to stakeholders?
