**Problem:**

Let focus of parabola is $S(x,y)$ which touches the x-axis and $y=x$ at $(1,0)$ and $(1,1)$ respectively, then find the focus of parabola.

**Attempt:**

Honestly, I am lost on this. I don't know how to make use of the given information to find the focus. I need a few hints to start with this problem.

Any help is appreciated. Thanks!
