The Given problem is trying to find three strictly increasing numbers with consecutive or non−consecutive numbers in an array with the help of javascript. Understanding the Problem Before starting to write algorithms and programmes for the given problem first we will understand the logic behind the problem. Consider a set of array with some random numbers in it. So JavaScript allows us to loop through an array and maintain track of the smallest and second−smallest values in order to find three strictly rising numbers. In this algorithm, We will discover three strictly growing integers if a third value ... Read More
Python dictionaries are an unordered collection of key value pairs. In this tutorial we will see how we can add new key value pairs to an already defined dictionary. Below are the two approaches which we can use.Assigning a new key as subscriptWe add a new element to the dictionary by using a new key as a subscript and assigning it a value.ExampleCountryCodeDict = {"India": 91, "UK" : 44 , "USA" : 1} print(CountryCodeDict) CountryCodeDict["Spain"]= 34 print "After adding" print(CountryCodeDict)OutputRunning the above code gives us the following result −{'India': 91, 'USA': 1, 'UK': 44} After adding {'Spain': 34, 'India': 91, ...
