Here is a sample sudoku puzzle . Enter the values as it is into the user interface as below..
The Solution will be calculated once you click the solve the puzzle button.
GUI has been developed by me . this program uses backtracking algo implemented by Bob carpenter.. kudos to him.
public int countClumps(int[] nums) {
int clump=0;
for(int i=0; i<nums.length;i++){
if(i+1<nums.length && nums[i+1]==nums[i]){
clump++;
while(i+1<nums.length && nums[i+1]==nums[i]){
i++;
}
}
}
return clump;
}
public int[] squareUp(int n) {
int[] x=new int[n*n]; for(int i=1; i<=n ; i++){ for(int j=1; j<=i; j++ ) x[(i*n)-j]=j;
}
return x;
}
