Given three strings A, B and C. Each of these is a string of length N consisting of lowercase English letters. The task is to make all the strings equal by performing an operation where any character of any of the given strings can be replaced with any other character, print the count of minimum number of such operations required.
Input: A = “place”, B = “abcde”, C = “plybe”
A = “place”, B = “abcde”, C = “plybe”.
We can achieve the task in the minimum number of operations by performing six operations as follows:
Change the first character in B to ‘p’. B is now “pbcde”
Change the second character in B to ‘l’. B is now “plcde”
Change the third character in B and C to ‘a’. B and C are now “plade” and “plabe” respectively.
Change the fourth character in B to ‘c’. B is now “place”
Change the fourth character in C to ‘c’. C is now “place”
Input: A = “game”, B = “game”, C = “game”
Approach: Run a loop, check if the ith characters of all of the strings are equal then no operations are required. If two characters are equal then one operation is required and if all three characters are different then two operations are required.
Below is the implementation of the above approach:
- Minimum Number of Manipulations required to make two Strings Anagram Without Deletion of Character
- Minimum number of given operations required to make two strings equal
- Total character pairs from two strings, with equal number of set bits in their ascii value
- Find the minimum number of preprocess moves required to make two strings equal
- Using Counter() in Python to find minimum character removal to make two strings anagram
- Check if two strings can be made equal by swapping one character among each other
- Minimum move to end operations to make all strings equal
- Number of sub-strings that contain the given character exactly k times
- Minimum number of pairs required to make two strings same
- Minimum number of swaps to make two binary string equal
- Append a digit in the end to make the number equal to the length of the remaining string
- Number of ways to divide string in sub-strings such to make them in lexicographically increasing sequence
- Count number of binary strings such that there is no substring of length greater than or equal to 3 with all 1's
- Count of strings that become equal to one of the two strings after one removal
- Minimum operation require to make first and last character same
