Tips to consider:
If input array is sorted then
- Binary search
- Two pointers
If asked for all permutations/subsets then
- Backtracking
If given a tree then
- DFS
- BFS
If given a graph then
- DFS
- BFS
If given a linked list then
- Two pointers
If recursion is banned then
- Stack
If must solve in-place then
- Swap corresponding values
- Store one or more different values in the same pointer
If asked for maximum/minimum subarray/subset/options then
- Dynamic programming
If asked for top/least K items then
- Heap
If asked for common strings then
- Map
- Trie
Else
- Map/Set for O(1) time & O(n) space
- Sort input for O(nlogn) time and O(1) space

Repost from N/a
30-for-30 plan: To improve at anything.
I’ve found way to work consistently .
The structure is simple:
• 30 days
• 30 minutes per day
With this approach, three things happen:
1. Clarity
It provides clarity on whether you are physically and psychologically invested in the thing you want to improve at.
30 days of effort is a real commitment.
If you are half-in, you won’t want to take it on and commit to the 30 days.
It’s a commitment razor.
2. Removes Intimidation
30-for-30 is small enough that you can mentally take it on.
Pre-start self-intimidation is one of the biggest drivers of stagnation.
We make something too daunting, so we don’t take it on.
New habits and improvement initiatives can often feel that way.
Example:
A lot of people say they want to get into great cardiovascular shape.
But if they’re currently out of shape, it can feel like a daunting task.
30-for-30 breaks the intimidation down into something reasonable and manageable.
30 minutes per day for 30 days. Simple.
3. Effective Compounding
30 days of 30 minutes per day is 900 total minutes of accumulated effort.
It can have surprisingly significant results.
There’s almost nothing in the world that you won’t improve at if you spend 900 minutes of focused, dedicated effort on it.
900 minutes of Zone 2 cardio puts you in much better cardiovascular shape.
900 minutes of writing makes you a dramatically better writer.
900 minutes of reading can cover several classic books and many articles.
900 minutes of meditation can build toward a clear mind.
30-for-30 works because it creates a marathon of short, manageable sprints.
It forces you to work like a lion, consistently.
Intensity plus consistency = progress.
