Python Program for Egg Dropping Puzzle

In this article, we will learn about the solution to the problem statement given below.

Problem statement − Suppose that we want to know which stories in a 40-story building are safe to drop the eggs from, and which of those will cause the eggs to get damaged on landing with the help of eggs. We need to display a minimum number of trails to check the stories.

Now let’s observe the solution in the implementation below −

Example

# dynamic programming
INT_MAX = 32767
# to get minimum trials
def eggDrop(n, k):
   # intialization
   eggFloor = [[0 for x in range(k + 1)] for x in range(n + 1)]
   # base case
   for i in range(1, n + 1):
      eggFloor[i][1] = 1
      eggFloor[i][0] = 0
   # We always need j trials
   for j in range(1, k + 1):
      eggFloor[1][j] = j
   # Fill rest of the entries
   for i in range(2, n + 1):
      for j in range(2, k + 1):
         eggFloor[i][j] = INT_MAX
         for x in range(1, j + 1):
            res = 1 + max(eggFloor[i-1][x-1], eggFloor[i][j-x])
            if res < eggFloor[i][j]:
               eggFloor[i][j] = res
   return eggFloor[n][k]
# main
n = 4
k = 40
print("Minimum number of trials in worst case scenario with " + str(n) + " eggs and "+ str(k) + " floors is " + str(eggDrop(n, k)))

Output

Minimum number of trials in worst case scenario with 4 eggs and 40 floors is 6

All the variables are declared in the local scope and their references are seen in the figure above.

Conclusion

In this article, we have learned about how we can make a Python Program for Egg Dropping Puzzle.
