Unfortunately I don’t remember the constraints now but I guess anything better than Brute Force should work, If i get the constraints I will let you know.

Uncertain Steps

Problem Description
Codu is trying to go down stairs from his building to ground floor.
He can go 3 ways:

  1. Walk 1 step at a time.
  2. Extend his legs and go 2 steps at a time.
  3. Jump down 3 steps at a time.
    Given n steps, calculate the number of possible ways to reach the ground floor, provided he can jump 3 steps at most once during this process.
    That is, he can jump down 3 steps only once, but at any time, if he wishes, while walking down the stairs.
    Constraints
    1 <= N <= 1000000.
    Input Format
    Single Integer denoting the number of Steps, N.
    Output
    Number of ways to reach ground floor.
    As the number can be huge, give output modulo 1000000007.
    Test Case
    Explanation
    Example 1
    Input
    4
    Output
    7
    Explanation
    1, 1, 1, 1
    1, 2, 1
    1, 1, 2
    1, 3
    2, 1, 1
    2, 2
    3, 1
    Number of ways = 7.

k=[]
for j in d :

for j in range(len(k)):
for f in range(len(k)):
if j<=f:
continue
elif k[j][0]==k[f][0]:
pair+=1
break
return pair
