$7\mathrm{.}2$T M $$ Hand Execution $-$ Arrays $-$ Part $2$

In this task we again hand execute a program using trace tables. This task also involves arrays.

The following is an example of how to represent an array for your hand execution using a trace table:

Tip: It is useful to include the indexes above the data. This will help make it easy to lookup the values in the array.

$123456789101112$

def whatshouldthisfunctionbecalled?$($data$,$ val$)$

i $=0$

result $=$ false

while i $<$ data.length

if data$[$i$]==$ val

result $=$ true

return result

end

i $=$ i $+1$

end

Complete a trace table $($using the answer sheet$)$ for the following two arrays and parameter values:
