Given a number of people N and an array of integers, each one representing the amount of people a type of umbrella can handle, output the minimum number of umbrellas needed to handle N people.
No umbrella could have left spaces. Which means if a umbrella can handle 2 people, there should be 2 people under it.
If there's no solution, return -1.

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
