text: /*
  When a contiguous block of text is selected in a PDF viewer, the selection is highlighted with a blue rectangle. In this PDF viewer, each word is highlighted independently. For example:
  
  PDF-highighting.png
  
  There is a list of 26 character heights aligned by index to their letters. For example, 'a' is at index 0 and 'z' is at index 25. There will also be a string. Using the letter heights given, determine the area of the rectangle highlight in mm^2 assuming all letters are 1mm wide.
  
  Example
  
  h = [1,3,1,3,1,4,1,3,2,5,5,5,5,1,1,5,5,1,5,2,5,5,5,5,5,5] word = 'torn'
  
  The heights are t = 2, o = 1, r = 1, and n = 1. The tallest letter is 2 high and there are 4 letters. The hightlighted area will be 2 * 4 = 8 mm^2 so the answer is 8.
  
  Function Description
  
  Complete the designerPdfViewer function in the editor below.
  
  designerPdfViewer has the following parameter(s):
  
  int h[26]: the heights of each letter
  string word: a string
  Returns
  
  int: the size of the highlighted area
  Input Format
  
  The first line contains 26 space-separated integers describing the respective heights of each consecutive lowercase English letter, ascii[a-z].
  The second line contains a single word consisting of lowercase English alphabetic letters.
  
  Constraints
  
  1 ≤ h[?] ≤ 7, where ? is an English lowercase letter.
  word contains no more than 10 letters.
  
  Sample Input 0
  
  1 3 1 3 1 4 1 3 2 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5
  abc
  Sample Output 0
  
  9
  Explanation 0
  
  We are highlighting the word abc:
  
  Letter heights are a = 1, b = 3 and c = 1. The tallest letter, b, is 3mm high. The selection area for this word is 3 * 1mm * 3mm = 9mm^2.
  
  Note: Recall that the width of each character is 1mm.
  
  Sample Input 1
  
  1 3 1 3 1 4 1 3 2 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 7
  zaba
  Sample Output 1
  
  28
  Explanation 1
  
  The tallest letter in zaba is z at 7mm. The selection area for this word is 4 * 1mm * 7mm = 28mm^2.
