Data Types

Task

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

1. Convert $secondInteger$ to an integer(Number type), then sum it with $firstInteger$ and print the result on a new line using console.log()

2. Convert $secondInteger$ to an floating-point number (Number type), then sum it with $firstDecimal$ and print result on a new line using console.log()

3. Print the concatenation of $firstString$ and $secondString$ on a new line using console.log(). Note that $firstString$ must be printed first.

Output Format

print the following three line of output:

1. On the first line, print the sum of $firstInteger$ and the integer representation of $secondInteger$.
2. On the second line, print the sum of $firstDecimal$ and the floating-point representation of $secondDeciaml$.
3. On the third line, print $firstString$ concatenated with $secondString$. You must print $firstString$ before $secondString$.
