Ans. Backtracking Approach
Approach:
 
In this approach, we will be trying to find the valid sequence using backtracking. We will be creating our sequence from left to right and will be trying to fix the biggest possible integer yet to be used at the current position.

Algorithm:
1. Make a variable ‘sum’, which will store the sum of all chocolates which are present in all N jars.
2. Now to find the starting speed, we’ll use the fact that our required speed has to be greater than the average speed(sum/M), else the ...read more
