Max Sum Given a sequence a[1],a[2],a[3]......a[n], your job is to calculate the max sum of a sub-sequence. For example, given (6,-1,5,4,-7), the max sum in this sequence is 6 + (-1) + 5 + 4 = 14. Input The first line of the input contains an integer…
A - Diverse Strings A string is called diverse if it contains consecutive (adjacent) letters of the Latin alphabet and each letter occurs exactly once. For example, the following strings are diverse: "fced", "xyz", "r" and &q…
D - Candies! Consider a sequence of digits of length [a1,a2,-,a]. We perform the following operation with it: replace pairs (a2i+1,a2i+2) with (a2i+1+a2i+2)mod10 for 0≤i<2k−1. For every i where a2i+1+a2i+2≥10 we get a candy! As a result, we will ge…
