Basic things for Motivation/ First Essential talk

Importance of Small Difference

• Example 1 :
  • Ask about Breaking Bad
  • discuss the importance of extra 3% clear crystals that walter white made
• Example 2 :
  • show Pictures of fastest man in India , Asia , World
  • discuss the impact of small millisec difference in timings
• Depict it with the equation - (1.01)^365 = 37.78

Qualities Essential to be the Best

• Ask about some essential qualities needed
• Discuss the importance of few -
  • Consistency
  • Persistance
  • Hardwork in right direction
  • The will power

Performace Equation

• Discuss about the Performace Equation - Performance = Potential - interference
• why the potential should be increased and interference should be decreased
• How can the performance be enhanced
  • Attend All Classes
  • Be Mindful
  • Learning is important

Many technologies, Where to start from?

• discuss about multiple technologies available , maybe ask students about some names

  • frontend - js,react , angular , vue etc
  • backend - java , python , ruby etc
  • Machine Learning

• introduce Data structures and Algorithms

  • define and differentiate
    • Data Structure - Something we need to organise data / keep data / Store data = Algorithms - the process / the steps
    • give an example of toothbrush being placed in kitchen
  • discuss about the importance of Data structures and Algorithms
  • Eventually reach to the conclusion that Data structure and Algorithms are important

Building a site more important than learning about Data Structures and Algorithms ?**

• Ask the question and then discuss the result with examples

• Example 1 : E-Commerce

  • Dicuss the flow from searching a product to buying it
  • Discuss why we need Data structures and Algorithms in following functionalities
    • Searching a Product - need to be fast
    • Sorting - basis of price , category , reviews etc
    • Search typeahead - throw the name of trie just to introduce a wow-factor
    • Concurrency problem - 1 product , 2 buyers
  • Eventually convince that DSA is more important than just building a site

• Example 2 : Food Delivery

  • Finding nearest restaurant
  • Sorting the list of restaurant - basis of name , reviews , location
  • Utilisation of resources (Explain with the help of diagram)
    • Shortest path of delivery
    • Shortest time is another factor to consider
    • more factors which finally helps in better utilisation of resources

• Ask if it's now clear that DSA is the basic building block

How Problem Solving works?

• Dicuss about the computer and decision making

• How the computer doesn't have mind of its own

• How every step needed to be told to computer based on several decisions

• Example 1 : ATM Machine

  • Discuss the process outline
  • Discuss the process in detail using decision tree (Don't introduce the name yet)
  • after drawing a basic decision tree - introduce with the name "Decision Tree"
  • Keep on focusing on the importance of decisions in problem solving
