This can be solved using graph coloring problem ! A[] = array of shows( names/nos ). B[] = start times in order. C[] = end times in order. Let G(V,E ) be our graph where V = shows. There exists an edge between any two vertices if their timings overlap . O(n^2) to create the graph. ( and overall Tn ). Now with graph coloring comes in. The nodes which have different colour can be seen fully ! We do this with BFS ( O(v+e) ). @Arjun Sir, kindly do check my logic here [...]

Consider a disk which has 64 tracks , in every track there are 1024 sectors , each sector has 2048 B . The disk is moving with 3000 RPM . Let the avg seek time is 10 ms and it is required to read a file of 64KB which was placed in outer track from 32 sector onwards . The current position of read/write head is 16th sector of inner track. What is the time taken to complete disk read operation? [...]

how to Implement arrays using linked lists (and vice versa)?

how to Implement arrays using linked lists (and vice versa)? Like if we implement a linked list using an array….then we can maintain two arrays. In one array we will maintain the data and in another array, we will store the address of the node..and we will maintain it accordingly, whether this is correct? Also how to implement an array using a linked list..is this even possible? [...]

We have $(D\to E), (\neg E \to A), (\neg B \to \neg C), (F \to \neg H), (\neg A \to B) $ Now, we have $(D,C)$ inside the hideout. So, $E$ must also be inside (due to $D \to E),$ and $B$ must also be inside due to $([\neg B \to \neg C] \leftrightarrow [C \to B]).$ This eliminates options A, B and C. Correct answer: D. [...]

Relative speed of the dog, $S_r = \dfrac{(2 \times 2m) – (3 \times 1m)}{t},$ where $t$ is the time for two leaps of the dog. $\implies S_r = 1m/t$ So, after every $2$ leaps, the dog covers $1m$ distance to the fox. So, to cover $30\;m$ dog will need to make $2 \times 30 = 60$ leaps which will be $2 \times 60 = 120m$. Correct option: D. [...]
