I have sql database developer background and want to switch to SWE and decided to practice leetcode. I picked the array data structure, easiet of them all. But I was struggling with coming up with writing the code and was thinking of using for loops and if/then statements. But whem I saw the solution they are using fucntions like all, enumeration from python.

I can understand the solutions andhave started practicing python to learn. I have programming skills and have created CRUD applications in c#/asp.net.

My question is how do I get exposure to lot of these types of quetions. Do I first try for 15 minutes and then open the solution. It took me 2 -3 hours over 3-4 days to do the Find Pivot Index. then I looked at the solution.

Can anyone give me ideas on how do I go about preparing myself for SWE role.

Thank you
