Hello fellow leetcoders!
If remembering how you solved problems earlier has become a headache for you, I developed a chrome extension that analyses and tracks your submissions and schedules their revision based on your proficiency. It helped me get fairly good at problem solving and I hope it helps you too. It's available for chrome and edge browser and you can download it for free from https://leetrecur.namanshrimali.com.

Ps, if you're interested in what pushed me to develop this, you can read it in the comment section. It's an interesting read!
