Re: Want the problems of BDIO '11 contest
there was a problem:
PRINT A-Z and Z-A
মানে A থেকে Z আর Z থেকে A প্রিন্ট কর।
জানি না এইডা কেন দিছিল, কিন্তু দিছিল এবং আমি সর্বসাফল্যে এইটা পারছিলাম

Calculating Trigonometric Functions
Write a program to calculate any trigonometric functions(ie. $sin$,$cos$,$tan$ etc).
Please write the alogarithm or the logic. If u code in C/C++, skip using the header file math.h

Re: Dhaka Secondary 2009/5
but how can we get $a_{2009}$ from this equation?*Mahi* wrote:$a_n=2+a_0 \cdot a_1 \cdot a_2 \cdot a_3 \cdots a_{n-1}$ So $a_n-2=a_0 \cdot a_1 \cdot a_2 \cdot a_3 \cdots a_{n-1}$
Or, $a_{n}(a_n-2)+2=2+a_0 \cdot a_1 \cdot a_2 \cdot a_3 \cdots a_{n-1} \cdot a_n = a_{n+1}$
