Clyde Westley Ang a grade 9 from Chiang Kai Shek College is also one of the honorable mentions in the recently concluded 2014 International Mathematical Olympiad. His partner John Albert Palupat grade 8 from Holy Rosary College is one of the gold medalists in Korea Mathematics International Competition held in Daejeon County, Korea in July this year.

This year, there are 210 contestants from China, Indonesia, Hongkong, Macau, Singapore, Malaysia, Kazakhstan, Mongolia and Philippines. 33 bagged the gold medal, 47 got silver medal, and the other 66 were bronze medalists.

The contest was held for two consecutive days. 4 hard problems in day 1 from algebra, geometry and number theory and 2 harder problems in day 2.

Here is one of the problems in day 1:

Given a positive integer n.Let $a_1,a_2,\ldots,a_n$ be a sequence of nonnegative integers.Sequence of one or consecutive terms of $a_1,a_2,\ldots,a_n$ is called dragon if their arithmetic mean is bigger than 1.If a sequence is a dragon,then its first term is the head and the last term is the tail.Suppose $a_1,a_2,\ldots,a_n$ is the head or/and tail of some dragon sequence,determine the minimum value of  $a_1+a_2+\ldots+a_n$  in terms of n.
