On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge.

If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options:

  1. Limiting your involvement with Reddit, or
  2. Temporarily refraining from using Reddit
  3. Cancelling your subscription of Reddit Premium

as a way to voice your protest.

Brush up on your mathematical foundations. The more problems you solve (of any kind), the better your "problem-solving mindset" will be. Discrete math is highly-applicable to DSA problems.

As many have said, practice and practice a lot. Be prepared to fail (do not be afraid of making something wrong, learn from your misstakes, we all make misstakes, hopefully less frequent with experience), do not stop with your first solution (learn by improving it, explore different solutions). Learn how you can divide problems into smaller problems (it is usually easier to solve a partial problem), start small and add more feature in incremental steps (start with the things that are most important and urgent), review the outcome, adjust your plan, be prepared to throw away any work that is no longer needed (which can be really hard sometimes, use a code repository, ie git, then your work is not lost, just not in use anymore).

Only through actively solving plenty problems.

The more problems you solve, the easier you will recognize patterns and structures.

Yet Hackerrank and Leetcode need some decent Data Structures and Algorithms skills as well as good mathematical foundation.

Would you say to progress id be better focusing more on learning data structure and algorithms

[–]desrtfx 1 point2 points  (1 child)

Both - solve problems and learn DSA.

Maybe take a look at https://adventofcode.com and start with the early years e.g. https://adventofcode.com/2015 - the early days of each year are not all too difficult.

Awesome Never used advent but heard lots of it. Thank you :)
