Some DNA sequences exist in circular forms as in the following figure, which shows a circular sequence "CGAGTCAGCT", that is, the last symbol "T" in "CGAGTCAGCT" is connected to the first symbol "C". We always rea…
Problem B Number Sequence Input: standard input Output: standard output Time Limit: 1 second A single positive integer i is given. Write a program to find the digit located in the position i in the sequence of number groups S1S2…Sk. Each group Sk con…
Ducci Sequence Time Limit:3000MS Memory Limit:0KB 64bit IO Format:%lld & %llu Description A Ducci sequence is a sequence of n-tuples of integers. Given an n-tuple of integers (a1, a2, ... , an), the next n-tuple in the sequence is fo…
Ducci Sequence Description A Ducci sequence is a sequence of n-tuples of integers. Given an n-tuple of integers (a1, a2, ... , an), the next n-tuple in the sequence is formed by taking the absolute differences of neighboring integers: ( a1, a2, ...…
A Ducci sequence is a sequence of n-tuples of integers. Given an n-tuple of integers (a1, a2, · · · , an), the next n-tuple in the sequence is formed by taking the absolute differences of neighboring integers: (a1, a2, · · · , an) → (|a1 − a2|, |a2 −…
Wavio Sequence Wavio is a sequence of integers. It has some interesting properties. · Wavio is of odd length i.e. L = 2*n + 1. · The first (n+1) integers of Wavio sequence makes a strictly increasing sequence. · The last (n+1) integers of Wavio s…
