The actions of the virus can be represented using the following context-free grammar: where V is the virus, a and b are acid and base molecules respectively.
V→ aVb
V→ bVa
V→ VV
V→ ε
The language of the above grammar is the set of strings consisting of an equal number of a’s and b’s. A sequence of acid and base molecules is just a string over {a, b}. To check if a single virus could have produced the sequence, you can use CYK algorithm to check membership in the above context-free grammar.

it is better and safer to use (!list) than (list==NULL) as while implementation there might be some memory - segmentation fault errors.

Please ask you questions in the doubt section of techtud , rather than commenting on a previously asked question. This will increase the visibility of your question .

Now,

Let 60 % of mangoes weigh X grams and,

40 % of mangoes weigh Y grams

Let total number of mangoes be "n".

A/Q

$350 = {X \over 0.6n}$  ⇒  $350*0.6 = {X \over n}$   ⇒  $210 = {X \over n}$     ------------------------- (1)

$400 = {Y \over 0.4n}$   ⇒ $400*0.4 = {Y \over n}$   ⇒   $160 = {Y \over n}$     --------------------------(2)

(1) + (2)

$210 + 160 = { X + Y \over n}$

⇒ $370 = {Total Wt. \over n}$

Therefore, Average Weight of mangoes = 370 grams

Correct answer is (C) 1, 0

we call with x = 1 and y = 1, then ptr points to the variable x and we change its value to 0. Now, we put that value using *ptr to the variable y, hence y gets 0. Now, we change back the value of ptr i.e. x to 1. So, finally x = 1 and y = 0.

Only address space is shared by all the threads in a process, all the others can be thread specific.
