410395: GYM104015 M The Sum of Good Numbers

Let's call a positive integer good if there is no digit 0 in its decimal representation.

For an array of a good numbers $$$a$$$, one found out that the sum of some two neighboring elements is equal to $$$x$$$ (i.e. $$$x = a_i + a_{i + 1}$$$ for some $$$i$$$). $$$x$$$ had turned out to be a good number as well.

Then the elements of the array $$$a$$$ were written out one after another without separators into one string $$$s$$$. For example, if $$$a = [12, 5, 6, 133]$$$, then $$$s = 1256133$$$.

You are given a string $$$s$$$ and a number $$$x$$$. Your task is to determine the positions in the string that correspond to the adjacent elements of the array that have sum $$$x$$$. If there are several possible answers, you can print any of them.

The first line contains the string $$$s$$$ ($$$2 \le |s| \le 5 \cdot 10^5$$$).

The second line contains an integer $$$x$$$ ($$$2 \le x < 10^{200000}$$$).

An additional constraint on the input: the answer always exists, i.e you can always select two adjacent substrings of the string $$$s$$$ so that if you convert these substrings to integers, their sum is equal to $$$x$$$.

In the first line, print two integers $$$l_1$$$, $$$r_1$$$, meaning that the first term of the sum ($$$a_i$$$) is in the string $$$s$$$ from position $$$l_1$$$ to position $$$r_1$$$.

In the second line, print two integers $$$l_2$$$, $$$r_2$$$, meaning that the second term of the sum ($$$a_{i + 1}$$$) is in the string $$$s$$$ from position $$$l_2$$$ to position $$$r_2$$$.

In the first example $$$s[1;2] = 12$$$ and $$$s[3;3] = 5$$$, $$$12+5=17$$$.

In the second example $$$s[2;3] = 54$$$ and $$$s[4;6] = 471$$$, $$$54+471=525$$$.

In the third example $$$s[1;1] = 2$$$ and $$$s[2;2] = 3$$$, $$$2+3=5$$$.

In the fourth example $$$s[2;7] = 218633$$$ and $$$s[8;13] = 757639$$$, $$$218633+757639=976272$$$.
