REcuurence relation not clear

#1

multiplication factor arr[x]*arr[y+1] * arr[k+1]
why arr[k+1] this point not clear

#2

@dakshi,
What do you think it should be instead?

#3

matrix order is x ,k
and k+1,y
toh multiplation factor mein arr[k+1] hona chaihe yaa arr[k]
my question is this

#4

@dakshi,
That is not even a valid matrix order, it should be
M1{arr[x] , arr[k+1]} * M2{arr[k+1],arr[y]}
where M{m,n} means Matrix of size m * n.
