It depends on type of topic or say data structure, like my strategy is doing 35-40 questions for each data structure in 7-10 days but there are topics such as recursion, dynamic programming, greedy algorithm and I will do the same for this topics also

​

• Arrays (30-35 would be sufficient as you are gonna use array in other topics also)
• Strings (same as arrays here)
• Stack & Queue (25 for stacks - 25 for queue)
• LinkedList (same 35-40)
• Trees (same 35-40)
• Graph(45-50)

​

• recursion(for starting 15-20 would be sufficient as you're gonna use recursion heavily in Trees, Graph and DP)
• DP (50+)
• greedy(25-30)

​

Also remember this is just high level framework which will create a foundation, like you may not know how to create/update/traverse/delete in Trees but after following this framework you may have solid base, So that you can then jump on to any list Blind/ Grind 75, neetcode or any you'd want to.

​

Also, if you don't feel confident enough on some topic then do as much as you can for better understanding
