Consider the following pseudocode, assuming dynamic scoping rules:

procedure main$()$

x: int :$=3$

y: int:$=5$

procedure mult$()$

x:$=$ x$*$y

print$($x$)$

procedure three$($f:procedure$)$

x: int :$=7$

f$()$

procedure two$()$

y: int :$=9$

one$($three $,$ mult$)$

procedure one$($f$1$: procedure, f$2$:procedure$)$

x:int :$=1$

f$1($f$2)$

$//$main body

two$()$

print$($x$)$

If the language uses deep binding, what will the output be$?$ Explain your answer
