let arr = [[1, 2, 3], [4, 5, 6], [7, 8, 9]];
console.log(arr);
for(let i = arr.length; i >= 0; i--){
console.log(arr);
for(let j = arr.length; j >= 0; j--){
console.log(arr[j]);
}
}
let arr = [[1, 2, 3], [4, 5, 6], [7, 8, 9]];
console.log(arr);
for(let i = arr.length; i >= 0; i--){
console.log(arr);
for(let j = arr.length; j >= 0; j--){
