Given two strings *A* and *B* and these strings contain lower case letters. The task is to tell the length of the merged strings. For example, given *A is “abcde”* and *B is “cdefg”*, then merging the two strings results in “abcdefg”. The merge operation is performed in such a manner that the joining characters are both the *suffix of A* and *Prefix of B*.

Before merging you are allowed to do any ONE of the following operations:

- Reverse string A
- Reverse string B

**Examples:**

Input :A = "ababc" B = "bcabc"Output :Length is 8 the suffix of string A i.e "bc" and prefix of B i.e "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 i.e "fg" and prefix of reversed B i.e "fg" is the same so the merged string will be "cdefghba" and length is 8Input :A = "wxyz" B = "zyxw"Output :Length is 4

**Below is the Python code implementation of the above mentioned approach.**

`# function to find the length of the` `# merged 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 below statement to` ` ` `# know what the merged string is` ` ` `# print(a + b[k:])` ` ` `return` `len` `(a ` `+` `b[k:])` ` ` `# function to find the minimum length` `# among the merged string` `def` `merger(a, b):` ` ` `# reverse b ` ` ` `b1 ` `=` `b[::` `-` `1` `] ` ` ` ` ` `# function call to find the length` ` ` `# of string without reversing string 'B'` ` ` `r1 ` `=` `mergedstring(a, b)` ` ` ` ` `# function call to find the length` ` ` `# of the string by reversing string '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)` |

**Output:**

Length is 8
