DCP-348: Marvel Smartest Vol. 2 Back to All Problems

Medium Divide and Conquer > Dynamic Programming

Tony Stark can’t believe it. Dr.Doom is back. One of the smartest anti-heroes alive in Marvel Universe. “I can’t recognize you.” said, Iron Man. “Well , the scars in my face?They are gone now, through mystical things”, replied the dethroned ruler of Latveria. Tony said in a cold voice, “Let me check again: I will ask you a question. You need to answer it within **2** minutes to prove that you are indeed the smart, genius and equally frightening Dr.Victor Von Doom, standing in front of me. And the question is-In how many ways you can express an integer **n** ( **2<=n<=100000**) as the sum of one or more integers who are greater than or equal to 2?” Input: ------ Input will consist of **N+1** lines in separate line( **1<=N <=100000**) First line will contain **N**, the number of values of **n**. Next N line will contain one integer each denoting the value of **n**. Output: ------- For each n, print the number of way you can express n as the sum of one or more integers greater than **2**. You should print the answer modulo **10^9+7**. Sample Input ------------ 3 3 4 5 Sample Output ------------- 1 2 3 Explanation: There are 3 inputs: n=3,4,5 For n=3, possible expressions are 3= { 3}=>1 way For n=4, possible expressions are 4={ 4 , 2+2}=>2 ways For n=5 , possible expressions are 5={5,2+3,3+2}=>3 ways
