Technical Round 1: Rearrange an array such that positive and negative numbers are at alternating positions. Staring from a positive integer. If there are extra positive or negative numbers place them at the end.
- Rearrange positive and negative numbers in O(n) time and O(1) extra space. Discussion about all approaches and time complexity of each.
Technical Round 2: Started with introduction and discussion on projects. Then 2 coding questions were asked.
string="abbbaa" and k=3.So output will be "" string ="abbahjjjddj" and k=2.So output will be "h".
Discussion on time complexities for each problem.
