Solution Hacker Rank - 30 Days of Code: Day 1

Task

Complete the code in the editor below. The variables i, d, and s are already declared and initialized for you.

You must:

Declare 3 variables: one of type int, one of type double, and one of type String. Read 3 lines of input from stdin (according to the sequence given in the Input Format section below) and initialize your 3 variables.

Use the + operator to perform the following operations:

1. Print the sum of i plus your int variable on a new line.
2. Print the sum of d plus your double variable to a scale of one decimal place on a new line.
3. Concatenate s with the string you read as input and print the result on a new line.

Solution

 1i = 4
 2d = 4.0
 3s = 'HackerRank '
 4# Declare second integer, double, and String variables.
 5a = int(input())
 6b = float(input())
 7c = str(input())
 8
 9# Print the sum of both integer variables on a new line.
10print(i + a)
11
12# Print the sum of the double variables on a new line.
13print("{}".format(d + b, '.1f'))
14
15# Concatenate and print the String variables on a new line
16# The 's' variable above should be printed first.
17print(s + c)
