1 Decomposition
Break your problems down into more manageable chunks
Find the sum of all the numbers between 1 and 200
Slide 10 - Slide
2 Pattern Recognition
What can you observe and learn from?
Find the sum of all the numbers between 1 and 200
1+200 = 201
2+199 = 201
Slide 11 - Slide
3 Abstraction
Identify similarities and differences in similar problems.
Find the sum of all the numbers between 1 and 200
1+200 = 201 200/2 = 100 pairs
2+199 = 201
Slide 12 - Slide
4 Algorithm design
Develop step-by-step instructions to solve this and similar problems.
Find the sum of all the numbers between 1 and 200
(1+200) * (200/2) = 20100
