This language was not initially on my list, but I found it on Wikipedia in the list of languages with built-in support for bignums (I would come to regret that). It is (somewhat) statically typed, with dynamic typing supported. Other than that, it looks like C with classes (so, C++ :) ).

The way bignum works in Pike is that when the numbers get too big to store in an int, they get implicitly, silently converted to the bignum format... a string. That works wonders with the silent conversion from int to string that you get when you do string + int. And when converting a number to bigint, if it's in an array, AFAIU the whole array gets converted to bigint. This leads to comical situations like: 2715 + 0 = 27150. Such laughter! The crowd roars! Endless comedic value.

To run it, save your input in input.txt and give the program input on stdin:

echo -n 1 | pike solution.pike
