Tensorflow is a machine learning framework that is provided by Google. It is an open−source framework used in conjunction with Python to implement algorithms, deep learning applications and much more. It is used in research and for production purposes.The ‘tensorflow’ package can be installed on Windows using the below line of code −pip install tensorflowThe ‘IMDB’ dataset contains reviews of over 50 thousand movies. This dataset is generally used with operations associated with Natural Language Processing.We are using the Google Colaboratory to run the below code.

This dataset is generally used with operations associated with Natural Language Processing.We are using the Google Colaboratory to run the below code. Google Colab or Colaboratory helps run Python code over the browser and requires zero configuration and free access to GPUs (Graphical Processing Units). Colaboratory has been built on top of ...

Frequency division multiplexing (FDM) is a technique of multiplexing, where the users are allowed the total available bandwidth on time sharing basis. Here the time domain is divided into several recurrent slots of fixed length, and each signal is allotted a time slot on a round-robin basis.Concept and ProcessIn TDM, the data flow of each input stream is divided into units. One unit may be 1 bit, 1 byte, or a block of few bytes. Each input unit is allotted an input time slot. One input unit corresponds to one output unit and is allotted an output time slot. During ...

Suppose we have an array of integers that is already sorted in the increasing order. We are required to write a JavaScript function that without using the inbuilt Array.prototype.sort() method sorts the array like the following −First number should be the maximumSecond number should be the minimumThird number should be the 2nd maximumFourth number should be the 2nd minimumAnd so on.For example −If the input array is −const arr = [1, 2, 3, 4, 5, 6];Then the output should be −const output = [ 6, 1, 5, 2, 4, 3 ];ExampleFollowing is the code −const arr = [1, 2, 3, ...

We are required to write a JavaScript function that takes in a string as the only argument. The task of our function is to count all the contiguous substrings in the input string that contains exactly one distinct letter.The function should then return the count of all such substrings.For example −If the input string is −const str = 'iiiji';Then the output should be −const output = 8;because the desired strings are −'iii', 'i', 'i', 'i', 'i', 'j', 'ii', 'ii'ExampleFollowing is the code −const str = 'iiiji'; const countSpecialStrings = (str = '') => { let { length } = ...

We are required to write a JavaScript function that takes in an positive integer as the only argument.The function should first count the sum of the digits of the number and then their product. Finally, the function should return the absolute difference of the product and the sum.For example −If the input number is −const num = 12345;Then the output should be −const output = 105;ExampleFollowing is the code −const num = 12345; const product = (num, res = 1) => { if(num){ return product(Math.floor(num / 10), res * (num % 10)); } return ...

We are required to write a JavaScript function that takes in an array of integers as the first and the only argument.The function is required to count the number of all such element pairs from the array that are equal in magnitude but are present at different indices.For example −If the input array is −const arr = [7, 9, 5, 7, 7, 5];Then the output should be −const output = 4;because the desired pairs are [7, 7], [7, 7], [7, 7], [5, 5]ExampleFollowing is the code −const arr = [7, 9, 5, 7, 7, 5]; const equalPairCount = (arr = ...

Armstrong Numbers: A positive integer is called an Armstrong number (of order n) if −abcd... = a^n + b^n + c^n + d^n + ...We are required to write a JavaScript function that takes in an array of exactly two numbers specifying a range.The function should return an array of all the Armstrong numbers that falls in that range (including the start and end numbers if they are Armstrong).We will first separately write a function to detect Armstrong numbers and then iterate through the range to fill the array with desired numbers.ExampleFollowing is the code −const range = [11, 1111]; ...

We are required to write a JavaScript function that takes in an array of integers as the first and the only argument.The function needs to determine whether there exists a combination of elements of the input array that when they are divided into two groups (may/may not have equal elements), the average of both the groups is just the same. If there exists any such condition the function should return true, false otherwise.For example −If the input array is −const arr = [6, 3, 2, 8, 1, 5, 7, 4];Then the output should be −const output = true;because the combination ...

Two strings str1 and str2 are similar if we can swap two letters (in different positions) of str1, so that it equals str2. Also, two strings str1 and str2 are similar if they are equal.For example, "tars" and "rats" are similar (swapping at positions 0 and 2), and "rats" and "arts" are similar, but "star" is not similar to "tars", "rats", or "arts".Together, these form two connected groups by similarity: {"tars", "rats", "arts"} and {"star"}. Notice that "tars" and "arts" are in the same group even though they are not similar.Formally, each group is such that a word is in ... Read More
