Check if all array elements can be reduced to 0 by repeatedly reducing pairs of consecutive elements by their minimum | Function to check if it is possible to convert the array.
Traverse the array range [ 1 , N - 1 ].
If arr [ i ] < arr [ i - 1 ].
Otherwise.
Decrement arr [ i ] by arr [ i - 1 ].
If arr [ n - 1 ] is not equal to zero.
Otherwise.
