Imagine a $2-$D space where every point is represented by their $2-$D coordinates $(x,y).$ Imagine you are currently on $(1,1).$

At any point of time, if you are on $(x,y),$ then you can either jump to $(x,x+y)$ or $(x+y,y).$ If you are currently on $(100,113),$ which point would you have been on just before $($a step before$)(100,113)?$

If there are multiple possibilities, please put $-1$ as the answer. If there is indeed one unique answer $(x,y),$ please concatenate $x$ and $y$ and then put the answer in the textbox below.

Note: Before concatenating, make sure to remove any padded zeroes or decimal points. For example, if the answer is $(1,2),$ then put $12$ in the textbox. You should not put $012,$ or $102,$ or $1\mathrm{.}02\mathrm{.}0$ or $1,2$ in the given textbox.
