For this algorithm, we simply do exactly what is described: sort nums, and return the element in question. To see why this will always return the majority element (given that the array has one), consider the figure below (the top example is for an odd-length array and the bottom is fo...
for each suffix in this bucket, find the position of sa + 2h, if we go out of bounds assign position = 0 So picture looks like this: a = 0, anana = 3, ana = 3 (since a + 1 > n, nana is in 3rd bucket and na is also in third bucket) Now, sort the assigned indices of ...

- Bucket sort consists of three steps: data bucketing, sorting within buckets, and merging results. It also embodies the divide-and-conquer strategy, suitable for very large datasets. The key to bucket sort is the even distribution of data. - Counting sort is a special case of bucket sort...

Let's take selection sort for example. In selection sort we find the lowest value, remove it, and insert it at the beginning. We could do the same with a linked list as well, right? We have just seen how to search through a linked list, how to remove a node, and how to insert ...
They can be used as the most important guideline for the wave counting. Below we describe the three rules:• Rule 1: Wave 2 can never retrace more than 100 percent of wave 1.• Rule 2: Wave 4 may never end in the price territory of wave 1.• Rule 3: Out of the three ...
