DAY 1- DATA TYPE ON HACKER RANK

TASK--> Three variable i, d and s are already declared and initialized for you, you must.

1. Declare 3 variable : One of type int, one of type double, one of type string.

2. Read 3 line of input from stdin and intilized your 3 variable.

3. Use + operator to perform following operation.

    a.)  Print sum of i plus your int variable on a new line.

    b.) Print sum of d Plus your double variable on a new line.

    c.) Concatenate S with the String you need as input & print the result on a new line.
