#Algorithms
Can somebody help me out to figure out an algorithm that would work in O(nlogn) for the following problem? Given a SORTED array of n elements. Find three numbers from the array that will add up to a given number k. My approach: Use two pointers ... I can't figure out when to increment L or when to decrement H, in case z is not found. Any ideas? Thank you

Test series: gatebook mock 2
Consider the collection of all un directed graphs with 10 nodes and 6 edges. Let M and m, respectively, be the maximum and minimum number of connected components in any graph in the collection. If a graph has no self loops and there is at most one edge between any pair ... m = 1 (C) M = 7, m = 4 (D) M = 6, m = 4 Shouldn't the answer be D?

gatebook mt2 qn 42
The intended purpose of this code is to precompute all the primes less than N. When it is finished executing, for r ∈ [2, N), bits[r] is supposed to equal 1 if and only if N is composite. Assume that the bits array is initialized to ... ; so why cant we just do a direct search? If it is 0 its prime, otherwise composite? What is the problem in this?

Hashing
Using open addressing with linear probing, we sequentially insert three distinct keys k1, k2 and k3 into a hash table of size m. Assuming simple uniform hashing, what is the probability that we will need three probes, when inserting the third key, k3? 3/m 2/m2 3/m2 2/m Please explain the solution.

Self Doubt
I came across few Compiler Design Doubts, Please provide your cent. $Q_1 :$ Can lexical analyser detect some/any type of errors? I think yes, because while scanning to identify tokens, it may be the cases that a string pattern doesn't match with any ... $\color{navy}{A \rightarrow aA}$(Right Linear). What can be said about $\color{navy}{A \rightarrow aAb}$
