Designer PDF Viewer

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

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:

Input:  h={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}, word="abc"
Output: 9

Approach

Java

public class DesignerPDFViewer {
    public static void main(String[] args) {
        int[] h = { 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 };
        String word = "abc";
        System.out.println(designerPdfViewer(h, word));
    }

    private static int designerPdfViewer(int[] h, String word) {

        int m = word.length();
        int c[] = new int[m];
        int k = 0;
        for (int j = 0; j < m; j++) {
            int x = 97;
            while (word.charAt(j) != x && x <= 122) {
                x++;
            }
            c[k] = h[x - 97];
            k++;
        }
        int large = c[0];
        for (int i = 1; i < m; i++) {
            if (c[i] > large)
                large = c[i];
        }
        return large * m;
    }
}
