Dot Product of Sparse vectors
https://leetcode.com/discuss/interview-question/124823/
- Find an efficient way to represent a vector (1,1,1,1,1,1,22,2,2,2,2,2,2,2,3,4,4,5,6,6,7,7,7,8,8,8,9,9,9,99,9,,1,1,1,1,1,1,2,3,34,3,4,,3,3,3,3....)
- Use the representation you come up with to compute dot product of two vectors
- Ex: If you come up with MyDataStructure to represent a vector, then your function signature will be
int dotProduct(MyDataStructure vector1, MyDataStructure vector2)
// dot product of two vectors [1,2,3,4] and [5,6,7,8] is 1 * 5 + 2 * 6 + 3 * 7 + 4 * 8 - Take advantage of your "efficient" representation to compute the dot product faster.
- Ex: If you come up with MyDataStructure to represent a vector, then your function signature will be
https://leetcode.com/problems/random-pick-with-weight/
Some questions are the closest that it can get to the actual question. Like Russian Doll envelopes or Task Scheduler.
