$1.$ Dice roll On rolling a single die, we get six distinct outcomes $(1,2,3,4,5,6).$ On rolling two dice, we get $21$ distinct outcomes $((1,1),(2,3),(4,6),...).$ Note that getting $(2,3),$ for example, is considered same as getting $(3,2).$ Write a program to print the number of distinct outcomes when $"$n$"$ dice are rolled. Input format There is only one line of input containing a single positive integer x$.$ Constraints $030$ Only combinations must be counted, not permutations. For example, if $2$ dice are rolled, the outcome $(12)-1$ in the first dice and $2$ in the second dice is the same as the outcome $(21)-2$ in the first dice and I in the second dice. Output format The program or function must print out a single integer representing the distinct outcomes on the roll of x dice. Sample Input O Sample Output $06$ Explanation O There are $6$ possible outcomes on the roll of a single dice Sample input $12$ Sample output $121$ Explanation $1$ There are $21$ possible outcomes for the roll of $2$ dices: $(11)(12)(13)(14)(15)(16)$ Sample input $0$ Sample Output O Explanation O There are fi possible outcomes on the roll of a single dice Sample Input $12$ Sempla eutput $121$ Explanation $1$ There are $21$ possible outcomes for the roll of $2$ dices: $(11)(22)(13)(14)(15)(16)(22)(23)(24)(25)26)(33)(34)(35)(36)(44)(45)(46)(55)(56)(66)$ in java
