DSA - Day 3 - Boost Your Programming Skills: Problem Solving with HashMap & HashSet in Java DSA

DSA in Java - Day 3 - Hashing - II (Problem Solving on HashMap & HashSet) | Data Structures and Algorithms in Java

In this Video, we will learn about Hashing. We would be solving problems on HashSet and HashMap. This session would be very informative and engaging.
There will be 3 sessions for Hashing.

In real world , In hashing there is a hash function that maps keys to some values. But these hashing function may lead to collision that is two or more keys are mapped to same value. HashMap in Java stores the data in (Key, Value) pairs, and you can access them by an index of another type.HashSet in Java is a class from the Collections Framework. It allows you to store multiple values in a collection using a hash table. The hash table stores the values in an unordered method with the help of hashing mechanism.

How to improve coding skills ?
1. PRACTICE -- This is the key and hard way to achieve the ultimate .
2. Peer Programming --- Friends can be of great help.
3. Code Review -- Get you code reviewed from peers and seniors.
4. Debug -- A good problem solver , is always a good debugger.
5. Thinking with an open mind and having clarity of thoughts.

If not gone through the Introduction session on Hashing , please watch it :

Please go thorough the DSA conquered playlist :

There is a lot to learn, We have to go a long way together . Many ups and downs will come and go but remember one thing..................... " Why we started ? "
"First, solve the problem. Then, write the code."

Homework: Added in Video already or in the telegram group .
