Question
Consider the function computeS() whose pseudocode is given below:
Which ONE of the following values is returned by the function computeS() for ?
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() for ?
Correct answer
(C) [1, 1, 2, 1, 2]
