I. Code $1$ and the Problem It Solves $($Given as an Example$)$Tracing the code by specifying the line numbers in the order that they areexecuted. Explain what each line does. Since they are loops, some lines will beexecuted more than once. Please skip blank lines and the lines with $\}$ by itself.Output $($what are printedby the code$)4$: Assign $0$ to variable countHello!$6$: count is true, so keep goingHello!$7$: print Hello!Hello!$8$: Increase count by $1,$ so count changes from $0$ to $16$: count $(1)<mn\; id="EditorElement\_661414">3</mn>$ is true, so keep going$7$: print Hello!$8$: Increase count by $1,$ so count changes from $1$ to $26$: count $(2)<mtext\; id="EditorElement\_661519"></mtext><mn\; id="EditorElement\_661520">3</mn>$ is true, so keep going$7$: print Hello!$8$: Increase count by $1,$ so count changes from $2$ to $36$: count is false, so stop
