i think it would be T(n) = (logn)2 T(n/2) +c O(logn(log(logn)) not possible .

Ans is D) 2700If an integer constant starts with 0, it is considered an octal constant. So 0570 = 101 111 000 in binary as each octal digit can be directly converted to 3...

where i was fucked was . i learned learned and learned . never took test series seriously as there were a lot of wrong questions. what i focussed was on the type of quest...

$L=\{a^n c b^{2n}\}$$\quad=\{acbb,aacbbbb,aaacbbbbbb,\ldots\}$Here, $\textbf{c}$ acts as center. Push $2$ $a$'s for each $\textbf{a}$ and after $\textbf{c}$ start poppin...

if they ask that " atleast how many edges are there in multigraph"then our ans will be n-k ie 7 edges.??

A player in the Powerball lottery picks five different integers between 1 and 59, inclusive, and a sixth integer between 1 and 39, which may duplicate one of the earlier ...

Show that in a group of five people (where any two people are either friends or enemies), there are not necessarily three mutual friends or three mutual enemies.

You should know the precedence rule. $\to$ has higher precedence than quantification.

For empty string as language, q0 as final states gives 16 DFAs. But when both q0 and q1 are final states we must ensure none of the transitions go to q1 from q0. This red...

Instead of finding a function 'f' for the first MUX (in terms of z,x and y) and the second MUX (in terms of f , x and y), we can logically find out the answer.We can put ...
