Consider the function

int fun(x: integer)
{
    If x>100 then fun=x-10;
    else
    fun=fun(fun(x+11));
}

For the input $x=95$, the function will return

  1. $89$
  2. $90$
  3. $91$
  4. $92$

value return by fun(95)=fun(fun(106))=fun(96)=fun(fun(107))=fun(97)=fun(fun(108))=fun(98)=fun(fun(109))=fun(99)=fun(fun(110))=fun(100)=fun(fun(111))=fun(101)=91.

In a compact one-dimensional array representation for lower triangular matrix (all elements above diagonal are zero) of size $n\times n,$ non zero elements of each row are stored one after another, starting from first row, the index of $(i,j)^{th}$ element in this niw representation is $i+j$ $j+\dfrac{i(i-1)}{2}$ $i+j-1$ $i+\dfrac{j(j-1)}{2}$
