we discussed mainly my background and some of the works I did, but she was not able to understand most of them. She was constantly interrupting me and trying to change the subject. The part that really got in her nerve was when I did not know what is 'original content". She explained that she means shows like "Orange is the new black", etc. which I do not watch. It was completely incomprehensible for her that some people may spend their time reading papers, or help their church high school kids instead watching fictional stories about women in prison.
After you have decided which features to use, describe the process of constructing feature-vectors
Find the primitive (and derive) of log(x)
Each day a quarry-worker is given a pile of stones and told to reduce the larger stones into smaller ones. The worker must smash the stones together to reduce them, and is told to always pick up the largest two stones and smash them together. If the stones are of equal weight, they both disintegrate entirely. If one is larger, the smaller one is disintegrated and the larger one is reduced by the weight of the smaller one. Eventually, there is either one stone left that cannot be broken, or all of the stones have been smashed. Determine the weight of the last stone, or return O if there is none. Example weights = [1,2,3,6,7,7]. The worker always starts with the two largest stones. In this case, the two largest stones have equal weights of 7 so they both disintegrate when smashed. Next the worker smashes weights 3 and 6. The smaller one is destroyed and the larger weighs 6 - 3 = 3 units. Then, weights 3 and 2 are smashed together, which leaves a stone of weight 1. This is smashed with the last remaining stone of weight 1. There are no stones left, so the remaining stone weight is 0. Function Description Complete the function lastStoneWeight in the editor below. The function must return an integer that denotes the weight of the last stone, or 0 if all stones shattered into dust. lastStoneWeight has the following parameter(s): int weights[n]: an array of integers indicating the weights of each stone Constraints • 1 5n≤ 105 • 1 ≤ weights[i] ≤ 109
