Given the lists: \[ A = [1,2,3], \quad B = [4,5,6] \] Which of the following statements will result in \[ A = [1,2,3,4,5,6]? \]

Consider the following sets: \[ A = \{"this", "that"\}, \quad B = \{"that", "other"\}, \quad C = \{"other", "this"\} \] 

 Which of the following sets remain non-empty at the end?

Consider the following Python declarations of two lists.
\[ A = [1, 2, 3] \quad \text{and} \quad B = [4, 5, 6]. \] Which one of the following statements results in \( A = [1, 2, 3, 4, 5, 6] \)?

Consider the following Python code snippet. \[ A = \{\text{"this"}, \text{"that"}\}, \quad B = \{\text{"that"}, \text{"other"}\}, \quad C = \{\text{"other"}, \text{"this"}\} \] \[ \text{while "other" in C:} \] \[ \quad \text{if "this" in A:} \] \[ \quad \quad A, B, C = A - B, B - C, C - A \] \[ \quad \text{if "that" in B:} \] \[ \quad \quad A, B, C = C | A, A | B, B | C \] When the above program is executed, at the end, which of the following sets contains "this"?

Consider the following Python code :
def count (child_dict, i) :
if i not in child_dict.keys() :
return 1
ans = 1
for j in child_dict[i] :
ans += count (child_dict, j)
return ans
child_dict = dict()
child_dict [0] = [1, 2]
child_dict [1] = [3, 4, 5]
child_dict [2] = [6, 7, 8]
print (count(child_dict,0))
Which ONE of the following is the output of this code ?

Consider the following Python function :
def fun (D, s1, s2) :
if s1 s2:
D[s1], D[s2] = D[s2], D[sl]
fun (D, s1+1, s2-1)
What does this Python function fun () do? Select the ONE appropriate option below.

Consider the function computes (X) whose pseudocode is given below :
\(\frac{\text{computeS (X)}}{S[1] ←1}\)
for i ← 2 to length(X)
S[i] ← 1
if X[i-1] ≤ X[i]
S[i] ← S[i] + S[i - 1]
end if
end for
return S
Which ONE of the following values is returned by the function computeS (X) for X= [6, 3, 5, 4, 10] ?
