Ini adalah teka-teki yang terkenal. Katakan terdapat sebuah bangunan dengan n tingkat, jika kita mempunyai m telur, maka bagaimana kita mencari bilangan titisan minimum yang diperlukan ke lantai di mana kita boleh menjatuhkan telur dengan selamat tanpa memecahkannya.
Ada beberapa perkara penting yang perlu diingat -
Masukkan- bilangan telur dan lantai maksimum. Andaikan bilangan telur ialah 4 dan tingkat maksimum ialah 10.
Output- Bilangan minimum percubaan 4.
Input− bilangan telur, lantai maksimum.
Output − Dapatkan bilangan minimum ujian telur.
Begin define matrix of size [eggs+1, floors+1] for i:= 1 to eggs, do minTrial[i, 1] := 1 minTrial[i, 0] := 0 done for j := 1 to floors, do minTrial[1, j] := j done for i := 2 to eggs, do for j := 2 to floors, do minTrial[i, j] := ∞ for k := 1 to j, do res := 1 + max of minTrial[i-1, k-1] and minTrial[i, j-k] if res < minTrial[i, j], then minTrial[i,j] := res done done done return minTrial[eggs, floors] End

Enter number of eggs: 4 Enter max Floor: 10 Minimum number of trials: 4
