You have a given set of prices in an Array, find at which price you should buy and at which price you should sell so that you maximize the gain

3 Answers

The idea for the linear solution is, that when the next price is lower than current minimum, you should sell all for the previous maximum and buy for the new minimum. It is actually similar to looking for maximum difference where the min is predecessor of max. Code for the linear solution: void sell_points(const vector& data) { cout data[max]) { max = i; } } // last run if (data[min] < data[max] && max != last_max) { cout << "Buy:\t#" << min << " (price: " << data[min] << ")" << endl; cout << "Sell:\t#" << max << " (price: " << data[max] << ")" << endl; } } Less

(the last_max check is actually not necessary, in the code I forgot to set it appropriately but it is not needed anyway) Less

The brute-force solution is to compare each price to those further on and to return the greatest gain. Otherwise I tried a linear solution but I was not sure about the solution. Less

How to avoid flow marks in an injection molded plastic part.

3 Answers

Product designer has to design the part with proper wall thickness and geometric details that assist the moldflow in molding process. Further, during the molding process, we adjust the molding pressure or temperature to speed up the mold flow so that the mold can be filled fast before the material sets in to form the flow mark. Less

Specify on your drawings critical dimensions so your suppliers can assess and understand the scope of what you need. Then when your supplier provides mold flow analysis it can be done with complete information. Less

This really depends on the part. There are general rules of thumb to be followed but some of it is trial and error. Less

Name 3 of your weaknesses

2 Answers

Be honest about what u lack in, but turn it around as an opportunity for better communication time management, organization, and cite the resources out there to help with this. Less

I hate this question because no one wants to talk about their weaknesses. Plus, if they already know who they want to hire this question just affirms their decision to hire or not hire you. Less
