Maximum difference between a number JavaScript
In this problem statement, our task is to write the function for finding the maximum difference between a number in an array with the usage of Javascript functionalities. So we will use a nested loop to get the difference between two numbers. Understanding the problem statement The above problem statement is saying to find the maximum difference between any two numbers in the given array of integer numbers. In simple terms we have to find the largest possible difference between any two numbers of the array in which the larger number appears after the smaller number. Suppose we have an ...
Read MoreWhat is Neurobiology?
Introduction Neurobiology is the study of the cells and tissues of the nervous system and how the brain works including the brain, spine, neural circuits, and nerves that work throughout the body. Neurobiology is a subset of both physiology and neuroscience. The full vertebrate nervous system includes both the central and peripheral nervous systems The central nervous system consists of the brain, retina, and spinal cord. The peripheral nervous system comprises of the nerves outside the central nervous system that connect it to the rest of the body. Neurobiology can include other scientific disciplines, such as molecular biology and gene ...
Read MoreMasking a string JavaScript
The above problem statement is about masking a substring within a string with the help of asterisks in Javascript. So we have to create a function to get the string with some hidden characters. Understanding the problem statement In the above problem statement we have to mask a substring within a string with the help of asterisks in Javascript. Masking a given string means we have to replace the certain characters in the given string with some other characters. Normally the asterisks used to hide sensitive information such as passwords, credit card numbers and other confidential data. Logic for the ...
Read MoreMapping values to keys JavaScript
In the given problem statement we have to write a method for mapping values to keys with the help of Javascript. So for doing this task we will use an object literal in Javascript. Understanding the problem statement So we have to find out the value for the given key and for doing this task we can use an object literal. An object is a data structure which can store the data in key-value pairs. So the keys are the identifier of the values. With the help of keys we can access the values. In Javascript there are several methods ...
Read MoreWhat is Fluorochrome?
Introduction Fluorochromes are photoreactive chemicals when absorbing light or energy, electrons are raised from the ground state to an excited state. Electrons return to the ground state by a variety of transitions which may involve the emission of a quantum of light. This effect is termed fluorescence. The emitted light will always be of lower energy, and hence longer wavelength, than the exciting light. As the color of the exciting and emitting light are different, they can be separated from one another by using optical filters. Fluorescent dyes or fluorochromes are commonly used as detection reagents in various applications such ...
Read MoreFinding Lucky Numbers in a Matrix in JavaScript
In the given problem statement we have to write a function to get the lucky numbers in a matrix with the help of Javascript. So we will implement this task with for loops and functions of Javascript. Understanding the problem statement The problem statement is asking us to find the lucky numbers in a given matrix. So the lucky number will be defined as a number in the matrix which is the minimum value for its own row and the maximum value for its column. For example we have a matrix [ [3, 7], [9, 11] ], in this ...
Read MoreWhat is a Super Integron?
Introduction Super-integron term was first applied in 1998 (but without definition) to the integron with a long cassette array on the small chromosome of Vibrio cholerae. The term has since been used for integrons of various cassette array lengths or for integrons on bacterial chromosomes (plasmids). The use of "super-integron" is now discouraged since its meaning is unclear. In more modern usage, an integron located on a bacterial chromosome is termed a sedentary chromosomal integron, and one associated with transposons or plasmids is called a mobile integron. Two groups of integrons are known: resistance integrons and super-integrons. Gene cassettes in ...
Read MoreHow to Insert a New Line Character in Linux Shell Script Output ?
In bash, a newline refers to a line's end and a text's beginning. In Linux/Unix operating systems, the new line character is represented as ", " which instructs the terminal to move the cursor to the beginning of the next line. Many text editors don't show it by default. Inserting a new line character has several important reasons − It helps format the output to be understood and readable. Separating the output into sections makes it easier to locate specific information. The newline is also used as a line break that identifies the end of a line in a ...
Read MoreJavaScript Count repeating letter
In this problem statement, our target is to count the repeating letter in the given string with the help of Javascript functionalities. So we can solve this problem with the help of loops and some built-in methods of Javascript. Logic for the given problem In the given problem statement we have to design a program to count the repeating letters in the given string. For implementing this task first we will create a blank object for count, array for repeated characters and another object for results. Then we will loop through every character in the string. So for every ...
Read MoreJavaScript - How to create nested unordered list based on nesting of array?
In this problem statement, our task is to to create a nested unordered list based on nesting of arrays with the help of Javascript. So for doing this task we will use a function to call recursively for each nested array and create a new unordered list.. Understanding the problem statement In the above problem statement we have to create a function for a nested list in HTML using Javascript. The input for the code will be an array that can have any number of items and can also include other arrays that represent nested lists. The code will be ...
