Re: [algogeeks] 400!
take an long array of integer (to store the answer)
let Mod=1 (maximum allowable size or number in the array element
initialize the last element of array with 1
and know start multiplying the 1--n into the last number to first of array
if any number crosses the given then take
m=a[i]/mod
and set a[i]=a[i]%Mod;
and add m to the next adjacent element
eg let calculating 5!
taken an array of integer and Mod=10
A={0,0,1}
mutliplying 1 in all from the back side
A={0,0,1}
multiplying 2
A={0,0,2}
multiplying 3
A={0,0,6}
multiplying 4
the number in the last element goes 24
so setting 24%10 =4 stetting it into the that element and adding
24/10=2 to the next
A=[0,2,4}
multiplying 5
4*5=20(setting 0 and adding 2 to next}
2*5+2=12(setting 2 and adding 1 to next)
0*5+1=1
so A={1,2,0}

Hi,
How do you define without extra space ?
Doing any order traversal either using recursion or using iteration is
going to take extra space .
If you are given a binary tree represented by pointers that points to
children nodes is it possible to do a heap sort without an array ?

Re: [algogeeks] Build BST from binary tree without extra space
@ashish i forgot recussion uses memory but if we have to do it without using stack also then pickup the root and add it to the bst and to fill the vacant position of root choose left node and make it root and to adjust previous right node at it to leaf eg : D / \ A E / \ B C add D to the BST and add E to the leaf A / \ B C / E adding E to the leaf node can be done memory without using extra memory.
