You are given two lines A and B, and these lines contain lowercase letters. The challenge is to specify the length of the merged strings. For example, if A — "Abcde", and B — "Cdefg" then concatenation of the two strings results in "abcdefg". The merge operation is performed such that the characters to be appended are suffix A and prefix B.
Before merging, you are allowed to perform ONE of the following operations:
- Backward Line A
- Backward Line B
Examples :
Input: A = "ababc" B = "bcabc" Output: Length is 8 the suffix of string A ie "bc" and prefix of B ie "bc" is the same so the merged string will be "ababcabc" and length is 8. Input: A = "cdefg" B = "abhgf" Output: Length is 8 the suffix of string A ie "fg" and prefix of reversed B ie "fg" is the same so the merged string will be "cdefghba" and length is 8 Input: A = "wxyz" B = "zyxw" Output: Length is 4
Below is the Python code implementation of the above approach.
# function to find length # concatenated string def mergedstring (x, y) : k = len (y) for i in range ( len (x)): if x [i:] = = y [: k]: break else : k = k - 1 # uncomment the following statement # know what a concatenated string is # print (a + b [k:]) return len (a + b [k:]) # function to find the minimum length # among the concatenated string def merger (a, b): # reverse b b1 = b [:: - 1 ] # function call to determine length # lines without backlines & # 39; B & # 39; r1 = mergedstring (a, b) # function call to determine length # lines by reversing line "B" r2 = mergedstring (a, b1) # compare between lengths if r1" r2: print ( "Length is" , r2) else : print ( "Length is" , r1) # driver code a = "abcbc" b = "bcabc" merger (a, b) |

Exit :
Length is 8
