Tip
Tip

Tip 1 : Do not rush into things. Learning takes time. Focus should be on the concepts and not just on leaving topics half-prepared. Devote 70% of both time and effort to DSA. I solved a total of around 500 questions on sites like GFG and Leetcode. Do not repeat similar questions just to increase the count of the number of questions
Tip 2 : Competitive Programming is a bonus and not a necessity, rather focus on core DSA based problems before trying CP. Do not pursue CP if you do not like it. Devote that extra time to core CS subjects and aptitude preparation.
Tip 3 : Projects play an important role too, do no ignore them. Try to get your hands dirty with a little bit of every field i.e., frontend, backend, and database.

Resume Tip
Resume tip

Tip 1 : Try to make a single-page resume. Highlight skills, projects, and work experience more than CGPA. Ensure proper spacing and font to maintain professionalism.
Tip 2 : Does not lie on a resume. Everything written on your resume must be known by you in and out.

Note:

1) A prime number is a number that has only two factors: 1 and the number itself.

2) 1 is not a prime number.

You will be given ‘Q’ queries. You need to implement a queue using two stacks according to those queries. Each query will belong to one of these three types:

1 ‘X’: Enqueue element ‘X’  into the end of the nth queue. Returns true after the element is enqueued.

2: Dequeue the element at the front of the nth queue. Returns -1 if the queue is empty, otherwise, returns the dequeued element.
Note:
Enqueue means adding an element to the end of the queue, while Dequeue means removing the element from the front of the queue.

You are given two strings 'str1' and 'str1'.


You have to tell whether these strings form an anagram pair or not.


The strings form an anagram pair if the letters of one string can be rearranged to form another string.

Pre-requisites:

Anagrams are defined as words or names that can be formed by rearranging the letters of another word. Such as "spar" can be formed by rearranging letters of "rasp". Hence, "spar" and "rasp" are anagrams. 

Other examples include:

'triangle' and 'integral'
'listen' and 'silent'
Note:
Since it is a binary problem, there is no partial marking. Marks will only be awarded if you get all the test cases correct.
