You do not really keep track of them.</p> <ul> <li><p>You forget which problems you did not do well on</p></li> <li><p>You do not know which areas you are not good at</p></li> <li><p>You can not easily look back at what you have done</p></li> </ul> <p>This happened to me too I decided to make a tool to help with this.</p> <h2> Introducing AlgoTrack </h2> <p>AlgoTrack is a desktop app that I made using C++ and Qt to help you keep track of your algorithm practice in a way.</p> <p>You can try AlgoTrack here:</p> <p><a href="https://popoviciGabriel.github.io/AlgoTrack/" rel="noopener noreferrer">https://popoviciGabriel.github.io/AlgoTrack/</a></p> <h2> Screenshots </h2> <h3> Dashboard </h3> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fuxbog1z1s492tpznx8hw.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fuxbog1z1s492tpznx8hw.png" alt=" " width="800" height="460"></a></p> <h3> Search &amp; filter </h3> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fg79doibh8ehgkz96w2os.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fg79doibh8ehgkz96w2os.png" alt=" " width="800" height="140"></a></p> <h3> Add problem </h3> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fsn6ggkmkgqx6d64iufwn.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fsn6ggkmkgqx6d64iufwn.png" alt=" " width="557" height="635"></a></p> <h2> Features </h2> <ul> <li><p>You can track problems from LeetCode or Codeforces or AtCoder</p></li> <li><p>You can see the status of each problem: solved or failed or in progress</p></li> <li><p>You can add tags for topics like dynamic programming or graphs</p></li> <li><p>You can write notes about mistakes and ideas</p></li> <li><p>You can track how long it takes to solve problems</p></li> <li><p>You can see statistics about your progress</p></li> </ul> <h2> Why I made it </h2> <p>After some time I realized that just solving more problems was not enough.</p> <p>If you do not keep track of what you failed at or how long it took or what you did wrong you will not get better quickly.</p> <p>I tried using spreadsheets. They became messy very fast.</p> <p>So I made a desktop app just for this.</p> <h2> Tech stack </h2> <ul> <li><p>I used C++</p></li> <li><p>I used Qt with Widgets</p></li> <li><p>I used STL</p></li> <li><p>I made my logic for filtering and statistics and search</p></li> </ul> <h2> What I learned </h2> <ul> <li><p>It is very important to separate the logic and the user interface</p></li> <li><p>Making your own tools can really improve your workflow</p></li> <li><p>Even simple ideas can become products</p></li> </ul> <h2> Links </h2> <p>You can visit the website here:</p> <p><a href="https://popoviciGabriel.github.io/AlgoTrack/" rel="noopener noreferrer">https://popoviciGabriel.github.io/AlgoTrack/</a></p> <p>You can see the code on GitHub here:</p> <p><a href="https://github.com/PopoviciGabriel/AlgoTrack" rel="noopener noreferrer">https://github.com/PopoviciGabriel/AlgoTrack</a></p> <p>If you are serious about practicing algorithms I would really like to hear your thoughts, about AlgoTrack.</p> cpp qt programming productivity
