Write a Java program to create a $9$ X $9$ sudoku problem. A sample of a $9$ x $9$ sudoku board is given below: The rules for the sudoku game are: i$)$ Each row must contain the digits $1-9$ without repetition ii$)$ Each column must contain the digits $1-9$ without repetition iii$)$ Each of the nine $3$ x $3$ sub$-$boxes of the grid must contain the digits $1-9$ without repetition Procedure: $1.$ Import java.util.Random package and use the nextInt$()$ method of the Random class to generate numbers between $1$ and $9$ for the sudoku board. $2.$ For each row, take a number from the user $($between $4$ and $6,$ both inclusive$).$ Then, randomly generate that number of distinct digits between $0$ and $8($both inclusive$)$ and assign $0$s to those corresponding cells of that row in the array. For instance, if the user types $4$ for the first row, then generate four distinct digits randomly using the nextInt$()$ method of the Random class. If the four digits are $0,3,5,$ and $8,$ then assign $0$ to $[0][0],[0][3],[0][5],$ and $[0][8]$ cells. Similarly, assign $0$s to specific cells from the $2$nd to $9$th rows. These $0$s will represent empty cells. $3.$ Now, randomly generate distinct digits within the range $1$ to $9$ and assign them to empty cells of nine rows and nine columns as per the rules of the sudoku board. $4.$ Repetition within a $3$ X $3$ block is allowed for this assignment. $5.$ You don$$t have to check whether the sudoku is solvable or not. $[$Hint: $1.$ nextInt$($n$)$ method returns a digit between $0$ and $($n$-1).$ To generate a digit from $0$ to $8$ for a cell index, call nextInt$(9)$ method. To generate a digit from $1$ to $9,$ use nextInt$(9)+1.2.$ First, fill in the empty cells of nine cells of the first row and first column with distinct digits from $1$ to $9.$ Then fill in the empty cells of the rest eight cells of the second row and second column as per the sudoku rule, and so on$.]$ DO NOT use any array$-$related built$-$in Java classes and methods. You can use the Scanner class of Java to read the user input. The sample input$/$ output is given below: $(20$ points$)$ Sample input: $($User$$s inputs are shown in bold$)$ Enter the empty cell number from $4$ to $6$ for each row Enter the number of empty cells of row $1$: $6$ Enter the number of empty cells of row $2$: $5$ Enter the number of empty cells of row $3$: $6$ Enter the number of empty cells of row $4$: $6$ Enter the number of empty cells of row $5$: $5$ Enter the number of empty cells of row $6$: $4$ Enter the number of empty cells of row $7$: $6$ Enter the number of empty cells of row $8$: $5$ Enter the number of empty cells of row $9$: $6$ Sample output: $530070000600195000098000060800060003400803001703024006060000280000419005000080079$
