Given 3 strings A, B and C, the task is to find the longest common sub-sequence in all three given sequences.
A = "geeks", B = "geeksfor",
C = "geeksforgeeks"
Explanation: "geeks"is the longest common
subsequence with length 5.
A = "abcd", B = "efgh", C = "ijkl"
Explanation: There's no common subsequence
in all the strings.
You don't need to read input or print anything. Your task is to complete the function LCSof3() which takes the strings A, B, C and their lengths n1, n2, n3 as input and returns the length of the longest common subsequence in all the 3 strings.
Expected Time Complexity: O(n1*n2*n3). Expected Auxiliary Space: O(n1*n2*n3).
