karlding / zigzagarray.cc
Created January 22, 2016 22:39
Because I'm silly and tried to use std::swap and make some "smart" optimizations without thinking on a HackerRank problem :(
// print out array in zigzag format
// time: O(n log n) = O(n log n) + O(n log n) + O(n)
// space: O(3n)
std::vector<int> zigZagArray(std::vector<int> intArray) {
std::vector<int> v(intArray);
// sort descending order
std::sort(intArray.rbegin(), intArray.rend());
// sort asc
std::sort(v.begin(), v.end());
