Assuming optimal is with respect to the total waiting time (a) is correct. Total waiting times are (a) 0 + 1.4 + 7 = 8.4, idle time = 1 (b) 0 + 5.6 + 14.6 = 20.1, idle time = 0.6 (c) 0 + 1.4 + 7 = 8.4, idle time = 1 (d) 0 + 9 + 14 = 23, idle time = 0 http://www.cs.uic.edu/~jbell/CourseNotes/OperatingSystems/5_CPU_Scheduling.html

The function terminates for all powers of $2$ (which is infinite), hence (i) is false and (ii) is TRUE. Let $n = 5. $ Now, recursive calls will go like $5 - 14 - 7 - 20 - 10 - 5 -$ And this goes into infinite recursion. And if we multiply $5$ with ... possible, there are infinite recursions possible (even considering this case only). So, (iv) is TRUE and (iii) is false. So, correct answer is (D).

Let $G$ be a weighted undirected graph and e be an edge with maximum weight in $G$. Suppose there is a minimum weight spanning tree in $G$ containing the edge $e$. Which of the following statements is always TRUE? There exists a cutset in $G$ having all edges of maximum ... in $G$ having all edges of maximum weight. Edge $e$ cannot be contained in a cycle. All edges in $G$ have the same weight.

Let $M = (K, Σ, Г, Δ, s, F)$ be a pushdown automaton, where $K = (s, f), F = \{f\}, \Sigma = \{a, b\}, Г = \{a\}$ and $Δ = \{((s, a, \epsilon), (s, a)), ((s, b, \epsilon), (s, a)), (( s, a, a), (f, \epsilon)), ((f, a, a), (f, \epsilon)), ((f, b, a), (f, \epsilon))\}$. Which one of the following strings is not a member of $L(M)$? $aaa$ $aabab$ $baaba$ $bab$

An array $X$ of $n$ distinct integers is interpreted as a complete binary tree. The index of the first element of the array is $0$. The index of the parent of element $X[i], i \neq 0$, is? $\left \lfloor \dfrac i 2 \right \rfloor$ $\left \lceil \dfrac{i-1}{2} \right \rceil$ $\left \lceil \dfrac i 2 \right \rceil$ $\left \lceil \dfrac i 2 \right \rceil - 1$

The formula used to compute an approximation for the second derivative of a function $f$ at a point $X_0$ is $\dfrac{f(x_0 +h) + f(x_0 – h)}{2}$ $\dfrac{f(x_0 +h) - f(x_0 – h)}{2h}$ $\dfrac{f(x_0 +h) + 2f(x_0) + f(x_0 – h)}{h^2}$ $\dfrac{f(x_0 +h) - 2f(x_0) + f(x_0 – h)}{h^2}$

24) a. It will depends on value of x.. U can decide others 3 process sequence I.e 3,5,6 Now x can come anywhere depending on its value.. Remember we shld gve it in increasing order to minimize response time

An Internet Service Provider (ISP) has the following chunk of CIDR-based IP addresses available with it: $245.248.128.0/20$. The ISP wants to give half of this chunk of addresses to Organization $A$, and a quarter to Organization $B$, while retaining the remaining with itself. Which of the ... $245.248.136.0/24 \text{ and } 245.248.132.0/21$
