Venkateswara reddy K. - "Form what I know I would state the following two points: Only 20% of google's $180B revenue comes from non-ad revenue sources.

Google cloud is at position 3 compared after Amazon AWS and Microsoft Azure. Typically only top 2 platforms take majority of stake in a lot of businesses. Google Cloud's Goal: Become one of the top two Cloud platforms in the world by deep"See full answer

Bamboo Y. - "Since the problem asks for a O(logN) solution, I have to assume that the numbers are already sorted, meaning the same number are adjacent to each other, the value of the numbers shouldn't matter, and they expect us to use Binary Search. First, we should analyze the pattern of a regular number array without a single disrupter. Index: 0 1 2 3 4. 5 6. 7. 8. 9 Array:[1, 1, 2, 2, 4, 4, 5, 5, 6, 6] notice the odd indexes are always referencing the second of the reoccurring numbers and t"See full answer

Ammro H. - "I am not sure if I agree with the approach taken in the mock video. Should FB build a tablet? is not the same as "Design FB tablet."

My answer will be to examine critical factors to decide to build tablet vs. to build apps for existing non-FB tablets (ipads and android tablets) Users"See full answer

Dev S. - "Since you have indicated that the drop has been from the past few days and it is the sales drop. Assumption 1: It is not a gradual decrease and something that has been seen in the last few days. My assumption is the e-commerce site is a google store site where google sells all the products.

Avon T. - "Initialize left pointer: Set a left pointer left to 0. Iterate through the array: Iterate through the array from left to right. If the current element is not 0, swap it with the element at the left pointer and increment left. Time complexity: O(n). The loop iterates through the entire array once, making it linear time. Space complexity: O(1). The algorithm operates in-place, modifying the input array directly without using additional data structures. "See full answer

Feature - Interactive Travel Itinerary Maps We had about ten days from the time we decided to include this new feature in the external launch. Usually, the biggest chunk of time in each release cycle was the sign-off from an external QA team. We fast-tracked the dev effort and completed the development of the feature in five days.
