Python Program to Remove Duplicate Elements From an Array
An array is a collection of elements of same data type, and each element in the array is identified by an index value. It is a simplest data structure where each data element can be accessed directly by only using its index number. Arrays in Python Python does not have a specific data structure to represent arrays. Here, we can use List an array. [6, 4, 1, 5, 9] 0 1 2 3 4 The indexing in python starts from 0. In the above block the integers 6, 4, 1, 5, ...
Read MorePython Program to Remove All Occurrences of an Element in an Array/List
An array is a collection of elements of homogeneous datatypes stored in contiguous memory locations. Python does not provide support for the built-in arrays. If you need to work with arrays you need to import the "array" module or, use the arrays in numpy library.We can use lists instead of arrays in Python. However, we cannot restrict the elements of a list to be of the same data type. The given task is to remove all the occurrences of an element in an array/list. i, e. we to remove the specified element including the duplicate elements. Let us understand how this ...
Read MorePython program to print an Array
The collection of homogenous elements within a single variable and in the contiguous memory location is known as array. The elements in array can be of any datatype but all the elements that are present in the array should be homogeneous, i.e., should belong to the same datatype. The arrays are a kind of special variables which actually store several values or elements in the name of a single variable with continuous memory locations which are accurately known as “ indices ”. Indices The word indices represents the plural form of index. The word index denotes the position of the ...
Read MorePython Program to Sort the 2D Array Across Columns
When a two dimensional array or a 2D array is declared, it is treated like a matrix. So, we know that a matrix consists of rows and columns. The process of sorting the elements that belong to a particular column of a matrix either in ascending order or in descending order is known as sorting a 2D array across columns. Let us consider an algorithm followed by an Input output scenario to understand the exact application of this concept. Input Output Scenario Consider a two dimensional array. arr = [[ 7, 9, 5, 7 ], [9, 5, 9, 4], ...
Read MorePython program to print the Boundary elements of a Matrix
Boundary Elements of a Matrix The elements that are not surrounded by any other elements that belong to the same matrix are known as Boundary elements. Using this phenomena, we can build a program. Let us consider an Input output scenario and then construct a program. Input Output Scenario Consider a matrix ( square matrix ) The Boundary elements are the elements except the middle elements of the matrix. The middle element(s) of the matrix is 5 and there are no other middle elements except 5. So, the Boundary elements are 9, 8, 7, 6, ...
Read MorePython program to find common array elements
While considering the multi-dimensional arrays as an example, there is a method that is capable of finding the common elements present within a multi-dimensional array - intersection_update(). This method is used in order to find the common or intersecting elements present within the same array which is multi-dimensional in nature. Let us consider an input output scenario and then proceed with a program. Input Output Scenarios Consider a 2D array which is multi-dimensional in nature. arr = [[1, 2, 3, 4], [3, 4, 5, 6], [7, 8, 3, 4], [4, 9, 8, 3], [4, 3, 10, 12]] The ...
Read MorePython Program to Check if two arrays are equal
There are several techniques that helps us to check whether the given arrays are equal or not. The comparison of an array will not depend on the indices of the elements, it will only compare whether that particular element in one array is present in the other array or not. Let us discuss few techniques that compares two arrays and checks whether they are equal or not. There are several techniques that helps us to check whether the given arrays are equal or not. The comparison of an array will not depend on the indices of the elements, it will ...
