Day0.DataTypes.js

// Objective

// Today, we're discussing data types. Check out the attached tutorial for more details.

// Task

// Variables named , , and  are declared for you in the editor below. You must use the  operator to perform the following sequence of operations:

// Convert  to an integer (Number type), then sum it with  and print the result on a new line using console.log.
// Convert  to a floating-point number (Number type), then sum it with  and print the result on a new line using console.log.
// Print the concatenation of  and  on a new line using console.log. Note that  must be printed first.
// Input Format

// Data Type	Parameter	Description
// string		The string representation of an integer you must sum with .
// string		The string representation of a floating-point number you must sum with .
// string		A string of one or more space-separated words you must append to .
// Output Format

// Print the following three lines of output:

// On the first line, print the sum of  and the integer representation of .
// On the second line, print the sum of  and the floating-point representation of .
// On the third line, print  concatenated with . You must print  before .
// Sample Input 0

// 12
// 4.32
// is the best place to learn and practice coding!
// Sample Output 0

// 16
// 8.32
// HackerRank is the best place to learn and practice coding!
// Explanation 0

// When we sum the integers  and , we get the integer . 
// When we sum the floating-point numbers  and , we get . When we concatenate HackerRank with is the best place to learn and practice coding!, we get HackerRank is the best place to learn and practice coding!.

// You will not pass this challenge if you attempt to assign the Sample Case values to your variables instead of following the instructions above.

/**
*   The variables 'firstInteger', 'firstDecimal', and 'firstString' are declared for you -- do not modify them.
*   Print three lines:
*   1. The sum of 'firstInteger' and the Number representation of 'secondInteger'.
*   2. The sum of 'firstDecimal' and the Number representation of 'secondDecimal'.
*   3. The concatenation of 'firstString' and 'secondString' ('firstString' must be first).
*
*	Parameter(s):
*   secondInteger - The string representation of an integer.
*   secondDecimal - The string representation of a floating-point number.
*   secondString - A string consisting of one or more space-separated words.
