Can you solve this real interview question? How Many Numbers Are Smaller Than the Current Number - Given the array nums, for each nums[i] find out how many numbers in the array are smaller than it. That is, for each nums[i] you have to count the number o
Leetcode is the program used by many tech companies to evaluate software engineers for technical roles. Tech companies such as Meta, Google and Amazon use it to keep tabs on the thousands of job applicants they evaluate. "Every time I mention interviews, I get frustrated comments about Leetcod...
Simultaneously, engage in regular practice on platforms like HackerRank and LeetCode. This dual approach establishes a strong foundation and takes you towards proficiency.Step 5: Craft your Data Visualization SkillsUnveiling insights through compelling visualizations is a crucial step for any data analyst...
UPD: Thanks all for your replies! After reading the replies, I finally get a useful idea. We all think that even if AI gets smarter than us, we can still have fun doing Codeforces. It's a great way to get better at solving programming problems, or just to feel good about tackling t...
See code below:Now, whenever you are able to find a recursion solution then please try to do it with memoization technique. It reduces the time complexity. So basically in this, we store the calculated result in an array and if we again encounter the same problem th...
it’s possible to prepare. Sergio recommends a book calledCracking the Coding Interview, which gives an overview of how interviews work at big companies like Amazon, Facebook, and Google. He also suggests usingLeetCode,HackerRank, andCodewarsto practice the type of problems that are likely to ...
all, we want to be able to solve complex coding problems. We also wanted to test it on a less well-known question. For our experiment, we will be testing Leetcode 214. Shortest Palindrome. It’s somewhat similar to Leetcode 3, as in it’s one of the most popular string problems. ...

Besides scheduled practice time, you can probably fit in more practice time in some or many days in different ways as well if you are serious. For example,I think it is good to memorize some problems at the beginning of each day, maybe a bit harder than you'd normally practice, and th...
With the interview season coming up, I did what every software engineer does to prepare for interviews - Leetcode. I enjoyed solving the questions there. I took my sweet time to try every approach, make sure my syntax was right, dry-run the algorithms with as many test cases I could, ...
