jump to level 1
type the programs output
a = \donkey\
b = \bird\
c = a, b
d = c
d0 = \tiger\
if (a is d0):
print(\f\)
if (b is d1):
print(\g\)
if (c is d):
print(\h\)

Explanation:

Step1: Assign initial variables

$a = \text{"donkey"},\ b = \text{"bird"},\ c = [a, b]$

Step2: Link list d to c

$d = c$ (d references same list as c)

Step3: Modify shared list

$d[0] = \text{"tiger"}$ (c[0] also becomes "tiger")

Step4: Test first identity check

$a$ is $\text{"donkey"}$, $d[0]$ is $\text{"tiger"}$ → condition false, no print.

Step5: Test second identity check

$b$ is $\text{"bird"}$, $d[1]$ is $\text{"bird"}$ → condition true, print "g".

Step6: Test third identity check

$c$ and $d$ reference same list → condition true, print "h".

Answer:

g
h
