What is the distance between two nodes called?
The distance between two successive nodes or antinodes is called one half of the wavelength. This is denoted as λ/2. In the above expression, the term wavelength is represented as λ and is calculated as the velocity of the wave divided by the frequency.
How many antinodes must be there between successive nodes?
Nodes and antinodes are known to generate the stationary waves. In a given stationary wave, the distance between any given two successive nodes or any two successive antinodes is always half of the wavelength.
How to calculate maximum distance between two elements?
A simple solution for this problem is to, one by one, pick each element from the array and find its first and last occurrence in the array and take the difference between the first and last occurrence for maximum distance. The time complexity for this approach is O (n 2 ).
How to find the minimum and maximum elements in an array?
Find the minimum and maximum elements of the array. Traverse the array and for every occurrence of the maximum element, calculate its distance from all occurrences of the minimum element in the array and update the minimum distance. After complete traversal of the array, print all the minimum distance obtained. Time Complexity: O (N2)
How to calculate the distance between two occurrences in an array?
An efficient solution to this problem is to use hashing. The idea is to traverse the input array and store the index of the first occurrence in a hash map. For every other occurrence, find the difference between the index and the first index stored in the hash map.
How to find the difference between two elements in an array?
In a map, each key has some value in it as array’s element and their indexes, if for each element there are two indexes found, then we are going to find the difference between those indexes and find the bigger difference between the previous “maxDistance” and the present one.
