This problem actually goes by another name, but to throw off cheaters, I'll use "folding" to describe the following property:
A folding sequence is a sequence of numbers where the difference between consecutive numbers in the sequence alternate in sign. A difference of 0 is defined to have no sign, so any sequence with consecutive repeating numbers is by definition a non-folding sequence.
To illustrate, these are folding sequences:
1
| #!/usr/bin/env bash | |
| # add repository for g++-5 | |
| sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test | |
| # add repository for clang-3.7 | |
| sudo add-apt-repository -y "deb http://llvm.org/apt/trusty/ llvm-toolchain-trusty-3.7 main" | |
| wget --quiet -O - http://llvm.org/apt/llvm-snapshot.gpg.key | sudo apt-key add - |
