I was trying to implement the test case in IntelliJ;
However, the output result was "[I@65b54208
", I don't understand why this is my result, how to show my result as an integer in the matrix?
public class SearchMatrix {
public static void main(String[] args) {
int matrix[][]={{0,1,3},{4,5,6},{7,8,9}};
SearchMatrix s = new SearchMatrix();
System.out.println(s.Binary(matrix,3));
}
public int[] Binary(int[][] matrix, int target){
int r= matrix.length;
int c= matrix[0].length;
int left=0;
int right=r*c-1;
while (left<=right){
int mid=left+(right-left)/2;
int row=mid/c;
int col=mid%c;
if (matrix[row][col]<target){
left= mid+1;
} else if (matrix[row][col]>target){
right= mid-1;
} else{
return new int[] {row,col};
}
}
return new int[] {-1,-1};
}
}
You can't just print array as a primitive variable. Printing the array will just output the hash code of the array (not the content you wish for). Either print each element by separate statements
int[] result = s.Binary(matrix,3);
System.out.println(result[0]);
System.out.println(result[1]);
Or use a built in function for printing contents of array from java.util.Arrays
package javadoc
System.out.println(Arrays.toString(s.Binary(matrix, 3)));
