Question

JAVA ONLY

2D Arrays: You have been given a 10x10 array of integers, called Puzzle. You are to process the array, so that it verifies that each column’s elements are equal to the column’s index. That is, all elements in column 0 should be a 0, all elements in column 1 should be a 1, and so on. (Do not create the array, it is already created, no need to create main either)

Answer 1

Answer

// Assuming Puzzle is already provided..
boolean valid = true;
for (int i = 0; i < Puzzle.length; i++) {
    for (int j = 0; j < Puzzle[i].length; j++) {
        if (Puzzle[i][j] != j) {
            valid = false;
        }
    }
}
System.out.println(valid);
