Consider a big party where a log register for guests entry and exit times is maintained. Is it possible to rotate a window 90 degrees if it has the same length and width. Code only answers are discouraged on SO. Let's build a solution to the problem step by step:- The first thing that comes to our mind is that whenever we try to get the third largest element, it will be much easier if the elements were in a sorted order i.e in ascending order from lowest to highest. To achieve the right bucket size (bsize) for this to work, we'll need to iterate through nums once to find the total range (hi - lo), then use that to figure out the absolute smallest possible maximum gap value ((hi - lo) / (nums.length - 1)). dp [time] = profit means that within the first time duration, we cam make at most profit money.
