Suppose we have a list of rectangles represented using its length and breadth. We can rotate any rectangle by 90 degrees so after rotating, the breadth will become length and vice-versa. We have to check whether we can sort the rectangles in non-increasing order of breadth.So, if the input is ... Read More
