Difference between en1 and en2, changed 7 character(s)
We have to calculate the number of integer-sequences of length-'n' having the 'k' properties.↵
(B[1],B[2]......B[n])↵

A property is of the following type :↵

t1,t2,t3 ↵
(which means max(B[t1],B[t2]) should be t3)↵

Constraints : ↵

1<=n,t1,t2<=15↵

1<=k<=225↵

1<=t3<=100000↵

Example :↵


Length : 2 ↵

(n = 2 )↵

k = 1 ,this property needs to be satisfied : max(B[1],B[2])=2 . ↵

Answer :

Number of possible sequences : 5↵

1)(0,2)↵

2)(2,0)↵

3)(2,2)↵

4)(2,1)↵

5)(1,2)↵
