After the 1st operation (X = 1), the array would be [1+5, 2+1, 3+2, 4+3, 5+4] =[6, 3, 5, 7, 9]
After 2nd operation (X = 0), the array would be [6+6, 3+3, 5+5, 7+7, 9+9] =[12, 6, 10, 14, 18]
Thus the correct answer would equal to = (12+6+10+14+18) % (10^9+7) = 60
in this one- 2nd operation mai [6+9, 3+6,5+3…] hoga right>? and not the one given in the explaination of the question please resolve this doubt asa
NO
given explanation is correct
in question it is given that
every element of the cyclic array would be replaced by the sum of itself and the element lying X positions behind it in the cyclic array.
if x ==1 -> 1 position behind
if x==0 -> same element will be added
