Write your own code that plot the solution of the DFQ of $\frac{\text{d}\text{e}\text{l}\text{y}}{\text{d}\text{e}\text{l}\text{x}}=x-y$ in Fig. $1.$

Figure $1$: Solution of the DFQ: $\frac{dy}{\text{d}\text{e}\text{l}\text{x}}=x-y.$

Use the Enler's method to compute and plot the solution. Use $h$ of $0\mathrm{.}1$ ws the distance between neighboring two points for the Euler's method.

The initial condition is $)=(-3.$
