+Task 1: Strong Password
+
+Submitted by: [42]Mohammad Sajid Anwar
+ __________________________________________________________________
+
+ You are given a string, $str.
+
+ Write a program to return the minimum number of steps required to make
+ the given string very strong password. If it is already strong then
+ return 0.
+
+ Criteria:
+- It must have at least 6 characters.
+- It must contains at least one lowercase letter, at least one upper case letter
+ and at least one digit.
+- It shouldn't contain 3 repeating characters in a row.
+
+ Following can be considered as one step:
+- Insert one character
+- Delete one character
+- Replace one character with another
+
+Example 1
+
+Input: $str = "a"
+Output: 5
+
+Example 2
+
+Input: $str = "aB2"
+Output: 3
+
+Example 3
+
+Input: $str = "PaaSW0rd"
+Output: 0
+
+Example 4
+
+Input: $str = "Paaasw0rd"
+Output: 1
+
+Example 5
+
+Input: $str = "aaaaa"
+Output: 2
