Matplotlib is a popular Python package that is used for data visualization.Visualizing data is a key step since it helps understand what is going on in the data without actually looking at the numbers and performing complicated computations.It helps in communicating the quantitative insights to the audience effectively.Matplotlib is used to create 2 dimensional plots with the data. It comes with an object oriented API that helps in embedding the plots in Python applications. Matplotlib can be used with IPython shells, Jupyter notebook, Spyder IDE and so on.It is written in Python. It is created using Numpy, which is the ... Read More

Suppose, we have a grid or a matrix of words. We have to check whether a given word is present in the grid or not. The word can be found in four ways, horizontally left and right and vertically up and down. If we can find the word we return True, otherwise False.So, if the input is likepghsfykdghtkghihnsjsojfghnrtyuinput_str = "python", then the output will be True.To solve this, we will follow these steps −Define a function find_grid() . This will take matrix, input_str, row_pos, col_pos, row_count, col_count, degreeif degree is same as size of input_str , thenreturn Trueif row_pos < ... Read More

Suppose, we are provided with a Binary Search Tree (BST) that contains integer values, and a number 'total'. We have to find out if there are any group of three elements in the provided BST where the addition of the three elements is equal to the supplied 'total' value.So, if the input is liketotal = 12, then the output will be True.To solve this, we will follow these steps −temp_list := a new list initialized with zeroinorder traverse the tree and put it in temp_listfor i in range 0 to (size of temp_list - 2), increase by 1, doleft := ...

Keras was developed as a part of research for the project ONEIROS (Open ended Neuro-Electronic Intelligent Robot Operating System). Keras is a deep learning API, which is written in Python. It is a high-level API that has a productive interface that helps solve machine learning problems. It runs on top of Tensorflow framework. It was built to help experiment in a quick manner. It provides essential abstractions and building blocks that are essential in developing and encapsulating machine learning solutions.It is highly scalable and comes with cross-platform abilities. This means Keras can be run on TPU or clusters of GPUs. ... Read More

Suppose, we have been provided with three strings and we are asked to find which of the strings are a Pangram, Lipogram, and a Pangrammatic Lipogram. A Pangram is a string or a sentence, where every letter in the alphabet appears at least once. A Lipogram is a string or a sentence where one or more letters in the alphabet do not appear. A Pangrammatic Lipogram is a string or sentence where all letters in the alphabet appear except one.So, if the input is like −pack my box with five dozen liquor jugs to stay in this mortal world or ...

Suppose, we are given a string that is made of only two letters a and b. We have to find out if the string is of the form anbn, or in other words it contains n number of a's followed by n number of b's. If true, we return 1 otherwise 0.So, if the input is like "aaaaaaaaaaaabbbbbbbbbbbb", then the output will be true.To solve this, we will follow these steps −length := length of input_stringfor initialize i := 0, when i < length, update (increase i by 1), do &minusif input_string[i] is not equal to 'a', then −Come out ...

Suppose, we are given a string that contains only lowercase letters. Our task is to find if there exists a substring in the given string that is a palindrome and is of even length. If found, we return 1 otherwise 0.So, if the input is like "afternoon", then the output will be true.To solve this, we will follow these steps −for initialize x := 0, when x < length of string - 1, increase x by 1, do −if string[x] is same as string[x + 1], then:return truereturn falseExample (C++)Let us see the following implementation to get better understanding − Live ...
