To "function nest" a string, you must:
Treat the first character as a function, and the following characters as the arguments to that function. For example, if the input string was
Hello, then the first step would be:H(ello)Then, repeat this same step for every substring. So we get:
H(ello) H(e(llo)) H(e(l(lo))) H(e(l(l(o))))
Your task is to write a program or function that "function nests" a string. For example, if the input string was Hello world!, then you should output:
H(e(l(l(o( (w(o(r(l(d(!)))))))))))
The input will only ever contain printable ASCII, and you may take the input and the output in any reasonable format. For example, STDIN/STDOUT, function arguments and return value, reading and writing to a file, etc.
For simplicity's sake, you may also assume the input will not contain parentheses, and will not be empty.
Input:
Nest a string
Output:
N(e(s(t( (a( (s(t(r(i(n(g))))))))))))
Input:
foobar
Output:
f(o(o(b(a(r)))))
Input:
1234567890
Output:
1(2(3(4(5(6(7(8(9(0)))))))))
Input:
code-golf
Output:
c(o(d(e(-(g(o(l(f))))))))
Input:
a
Output:
a
Input:
42
Output:
4(2)
As usual, all of our default rules and loopholes apply, and the shortest answer scored in bytes wins!
