Instructions:
A code ABCDEFGH where A, B, C, D, E, F, G, H are all digits, guards the secret formula of a high demand soft drink. The code should follow the following constraints:
1. The 2 digit number AB should be a multiple of 11.
2. The digit C should be a multiple of B.
3. The digit D should be a multiple of B.
4. The 2-digit number EF should be a multiple of the 2-digit number CD.
5. G and H can be any 2 consecutive digits from 1 to 9 such that G<H.
6. None of the digits should be zero or one.
Based on the information given above, answer the questions that follow.

    Is not equal to H.

    To find the code, follow these steps:

    1. Start by finding all possible two-digit numbers that are multiples of 11. These numbers are 11, 22, 33, 44, 55, 66, 77, and 88. Let's call this set of numbers X.

    2. Choose one number from set X as AB. For example, let's choose AB = 44.

    3. Find all possible values for B by dividing C and D by AB, and checking if the remainder is 0. For example, if AB = 44, then possible values for B are 1, 2, 4, 11, 22, and 44.

    4. Choose one value for B and find all possible values for C by multiplying B by a number. For example, if B = 4, then possible values for C are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, and 80.

    5. Choose one value for B and one value for C, then find all possible values for D by multiplying B by a number. For example, if B = 4 and C = 20, then possible values for D are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, and 80.

    6. Choose one value for B, one value for C, and one value for D. Find all possible two-digit numbers EF that are multiples of CD. For example, if B = 4, C = 20, and D = 40, then possible values for EF are 20, 40, 60, 80, and 100.

    7. Choose one value for B, one value for C, one value for D, and one value for EF. Find all possible values for G and H. G can be any digit from 1 to 9, and H can be the digit that comes after G. For example, if B = 4, C = 20, D = 40, and EF = 40, then possible values for G and H are 1 and 2, 2 and 3, 3 and 4, 4 and 5, 5 and 6, 6 and 7, 7 and 8, and 8 and 9.

    8. Repeat steps 2 to 7 for all possible values of AB.

    9. The code ABCDEFGH will be the combination of one value for AB, one value for B, one value for C, one value for D, one value for EF, and one value for G and H.

    Note: There may be multiple valid codes that satisfy all the constraints.
