LintCode has the most interview problems covering Google, Facebook, Linkedin, Amazon, Microsoft and so on. Note that the implementation doesnt create a single sorted list of all events, rather it individually sorts arr[] and dep[] arrays, and then uses merge process of merge sort to process them together as a single sorted array. To do this, we should sort the boxtypes array (B) in descending order by the number of units per box (B[i][1]). This doesn't pass the same 7 test cases that are failing for OP. Examples: Constraints: 1 <= <= k <= n <= 10^5 speed.length == n efficiency.length == n 1 <= speed [i] <= 10^5 Saving frequency of each number - Create Map
