Finally, return the maximum value from the array. A key principle that dynamic programming is based on is that the optimal solution to a problem depends on the solutions to its sub-problems. The main idea of dynamic programming is to consider a significant problem and break it into smaller, individualized components. Standard problems on Dynamic Programming: If you like GeeksforGeeks and would like to contribute, you can also write an article and mail your article to [emailprotected] See your article appearing on the GeeksforGeeks main page and help other Geeks.

Computer science: theory, graphics, AI, compilers, systems, Over the years, Ive had the chance to conduct mock interviews with dozens of developers preparing for interviews at top companies like Apple, Facebook, and Amazon. For example, once our algorithm checks the value of the first array item, 8, it will then scan the remaining values for 3 (e.g., 11 8 = 3). As people, its easy for us to quickly scan the sequence of numbers and promptly come up with the pair of 9 and 2. 0000007809 00000 n
