Please Login in order to post a comment. The function ord returns unicode code point for character. I mean what does this [ord c -ord 'a' ] do? Variable c contains lowercase characters from input. Now, we need height of each character stored in list size which is "0-indexed". Since, range 97, can be shifted to the required 0,25 by subtracting ASCII value of first-character i. Thus, one can also use ord c in place of ord c -ord 'a'. Somehow, I find latter more intuitive.

Finally, using it as index of size : size[ord c -ord 'a' ] returns height of the character stored in c. Notice how it is nearly identical; only that you used an array and I a list for finding the maximum size. Haskell is one of my favorite languages, it's known for its elegant and concise code. Anyway, what I used is also list. My experience in python is quite limited so correct me if I am wrong, but isn't size an array? Of course, you use a list comprehension to build it, but if it was a list then size[.

What I meant was that you mapped over the input using an array to find the maximum size, while I used a list to store the sizes. Actually, both size and word are lists. But lists in python allow O 1 access like arrays in other languages. The most important difference is that array can store only same data-type while single list can store multiple data-types. Though I understood what you meant, I just pointed out on a lighter note, that they are also called list!

There's really no need to calculate strlen every time you go through each of your loops, especially since C doesn't hold a reference to a strings length. For reference:. You can use List. You can always find the max height of the chars in h[] and multiply by that since more than likely one of those chars will be in that string. Or you can use maximum char height as a condition to exit the loop prematurely if height ever reaches that.We have attached the Questions and Answers in a pdf format at free of cost.
