Dynamic Programmingby Wiki
Dynamic programming is a fancy name for storing intermediate results and re-using the stored result instead of re-computing them each time.
Let's see an example of a dynamic programming problem. Once we solve the problem using dynamic programming, the formal technical definitions will be easier to follow.
Problem: You are given a grid of size n \times 2 and n tiles of size 2 \times 1. In how many different ways can you tile the grid such that the entire grid is covered and no tiles overlap. (The tiles look identical to each other. Two ways of tiling are different based on whether the tiles are placed horizontally or vertically).
Example: There are 3 possible ways of tiling a 3 \times 2 grid.
Three vertical tiles

Quick-sort: Video tutorial, pseudo-code (and in-place sorting)by Wiki
We want to sort an array with n elements. Quick-sort does this by breaking up the array into non-overlapping segments, sorting them separately and then combining the results.
For instance, suppose we have a box with slips of paper with numbers between 100 and 300 to be sorted. We could first separate the slips into two bunches: those with values below 200 and those with values above 200. We can sort these bunches separately. Since all the values in the second bunch are larger than those in the first bunch, we can combine them easily into a single sorted bunch. 
Hi , My Son is in 5th Std . He is really good in Maths also can solve small programs available on coding sites for kids . Based on his interest I would like him to go for IOI in future . How should we start about same ? Whether he should learn C or Python ? Whether there are any sites which can help kids to understand algorithms ? Please help . Your guidance on same is highly appreciable
Now I get it, I was misinterpreting question all this time. Actually after finish of each round, lead is not the difference between points of that round. But the lead is difference between the points achieved through all rounds including current round - Lakpa Tashi Bhutia
