Move to Right and left
Task
Your task is to Move Right and left. If the numbers combine, sum.
Example
[1, 2]
/\ /\
/ X \
[1, 2, 1, 2]
Another example
[1, 2, 3]
/\ /\ /\
/ X X \
[1, 2,\/ \ \
4, 2, 3]
Test cases
[1,2,3] => [1,2,4,2,3]
[4,2] => [4,2,4,2]
[1] => [1,0,1]...
Let \$ A \$ represent the alphabet, such that \$ A_1 = \$ a and \$ A_{26} = \$ z.
Let's define that a word \$ W = w_1 w_2 ... w_n \$ (where \$ w_c \in A\$) is in standard order if and only if:
\$ w_1 = A_1 \$, and
for \$ 2 \le i \le n \$, if \$ w_i = A_x \$ then \$ w_j = A_{x-1} \$ for some \$ j <
We have found a form of abuse that is very difficult for the system to counter:

Reversed Multiple Pair
Intro
A reversed multiple pair with number \$a\$ and number \$b\$ that satisfy the following property:
\$
a\times b = reversed( (a-1)\times b )
\$
Example
\$a=6, b=9\$
$$6\times9=54,5\times9=45$$
As you can see, \$45\$ is the reversed version of \$54\$.

Given two integ...
