Koko can decide her bananas-per-hour eating speed of k. Each hour, she chooses some pile of bananas and eats k bananas from that pile. If the pile has less than k bananas, she eats all of them instead and will not eat any more bananas during this hour. Koko likes to eat slowly but still wants to finish eating all the bananas before the guards ...

In the problem ” Koko Eating Bananas” we are given an array of size n which contains the number of bananas in each pile. In one hour Koko can eat at most K bananas. If the pile contains less than K bananas in that case if Koko finishes all bananas of that pile then she cannot start eating bananas from another pile in the same hour. Koko wants to ea...
The first and the most important thing to solve this problem is to bring out observations. Here are a few observations for our search interval: 1. Koko must eat at least one banana per hour. So this is the minimum value of K. let’s name it as Start 2. We can limit the maximum number of bananas Koko can eat in one hour to the maximum number of banan...
Time complexity
The time complexity of the above code isO(n*log(W))because we are performing a binary search between one and W this takes logW time and for each value, in the binary search, we are traversing the piles array. So the piles array is traversed logW times it makes the time complexity n*logW. Here n and W are the numbers of piles and the maximum number of bananas in a pile.
Space complexity
The space complexity of the above code is O(1)because we are using only a variable to store the answer. References
