What is algorithm for array?
Array is a container which can hold a fix number of items and these items should be of the same type. Most of the data structures make use of arrays to implement their algorithms. Following are the important terms to understand the concept of Array. Element − Each item stored in an array is called an element.
How do you write an algorithm for an array?
To declare the array, you need to specify a name and the type of data it will contain. To create it, you need to specify its length (the number of values). For example, the “long form” code shown at right makes an array of N numbers of type double, all initialized to 0.0. The first statement is the array declaration.
How to find all leaders in an array?
An element in an array X is called a leader if it is greater than all elements to the right of it in X. The best algorithm to find all leaders in an array. At the start the right most element will always be a leader. If an element is greater than our current_max, it will a leader.
Is the last element in an array always the leader?
Here no element present on the right side which is greater than the above numbers from there position. In the above example, the last element (ie, 21) is always the leader as it has no element on the right of it. 46, 95 are also leaders as no element is greater than them on the right of the array.
Which is the leader of the array 10?
Array may have more leaders.. consider the following array [10 9 8 6 ] then 10,9,8 are leaders of the array Work from the right hand end of the array, keeping track of the maximum value you have encountered. Every time that maximum increases or is equalled, that element is a leader by your definition.
Which is an example of an element that is a leader?
An element is leader if it is greater than all the elements to its right side. And the rightmost element is always a leader. For example int the array {16, 17, 4, 3, 5, 2}, leaders are 17, 5 and 2. Let the input array be arr[] and size of the array be size.
