The displayed content need resizing and effective utilization of space as most of content is of less use during solving the problem while the statement reading part and IDE part is visible only in less area which can be increased by removing the above part from the visuals and making an icon at top right or left corner for only to access if needed or wished.
I felt that my most of the time is getting wasted in scrolling which can easily be saved by effective utilization of the displayed content.
Thank you for the feedback. We will reduce the top bar of problem page in a week.
