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] ?

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 ?
