Largest Rectangle in a Histogram

**English**RU

"Your power to choose can never be taken from you.

It can be neglected and it can be ignored.

But if used, it can make all the difference."

― Steve Goodier

You have a histogram. Try to find the size of the biggest rectangle you can build out of the histogram bars.

**Input: **An array of all rectangles’ heights on the histogram.

**Output: **Area of the biggest rectangle.

**Example:**

largestHistogram([5]) == 5 largestHistogram([5, 3]) == 6 largestHistogram([1, 1, 4, 1]) == 4 largestHistogram([1, 1, 3, 1]) == 4 largestHistogram([2, 1, 4, 5, 1, 3, 3]) == 8

**How it is used: **There is no way the solution you come up with will be of any use in real life. So, just have fun here!

**Precondition:**

0 < len(data) < 1000
