GATE IT 2006 | Question: 47
Consider the depth-first-search of an undirected graph with $3$ vertices $P$, $Q$, and $R$. Let discovery time $d(u)$ represent the time instant when the vertex $u$ is first visited, and finish time $f(u)$ represent the time instant when the ... are two connected components, and $Q$ and $R$ are connected There are two connected components, and $P$ and $Q$ are connected

GATE CSE 2000 | Question: 2.7
Let $a, b, c, d$ be propositions. Assume that the equivalence $a ⇔ ( b \vee \neg b)$ and $b ⇔c$ hold. Then the truth-value of the formula $(a ∧ b) → (a ∧ c) ∨ d$ is always True False Same as the truth-value of $b$ Same as the truth-value of $d$

GATE CSE 2006 | Question: 39
We consider the addition of two $2's$ complement numbers $ b_{n-1}b_{n-2}\dots b_{0}$ and $a_{n-1}a_{n-2}\dots a_{0}$. A binary adder for adding unsigned binary numbers is used to add the two numbers. The sum is denoted by $ c_{n-1}c_{n-2}\dots c_{0}$ and the ... $ c_{out}\oplus c_{n-1}$ $ a_{n-1}\oplus b_{n-1}\oplus c_{n-1}$
