1)ans[j] array: contain the indices where its stops 1st to get minimum number of intermediate stop
for eg for input
6 3
0
1
3
4
7
10
ans[0]=2(index of 3),ans[1]=3(index of 4),ans[2]=4(index of 4),ans[3]=5(index of 10)
now in second loop i calculate the number of path
finding number of possible node between ans[i] and ans[i+1] which can be taken(it is counted by count variable)(0<=i<=no. of nodes in ans array)to reach arr[ans[i+2]]
now if path between A and B is X and path between B and C is Y then number of path=X.Y(variable mount)
