+        Making a URL From a String
+        ------------------------------------
+
+        Purpose : Making a URL by replacing the spaces with a key value entered
+        by the user
+        Method : string manipulation
+
+        Time Complexity : Worst Case - O(n), n = length of the string
+
+        Hint :
+        Take a blank string, and add data from the input string to the blank
+        string to prepare the final URL
+
+        Pseudocode :
+        --> Take a blank string s2
+        --> for i in [0,length of input string]
+                if(not a whitespace)
+                    add to s2
+                elif(whitespace and next place is also whitespace)
+                    return s2
+                elif(whitespace and next place not whitespace)
+                    add the key value to the blank string
+
+        Visualization:
+
+        Given String To Make URL :
+
+        "Python is love"
+
+        Key : "%20"
+
+        Break The Given String :  /*/ ----> whitespace
+
+        +--------+-------+----+-------+------+
+        | Python |  /*/  | is |  /*/  | love |
+        +--------+-------+----+-------+------+
+            ^              ^             ^
+            ^              ^             ^
+            ^              ^             ^
+
+            1              2             3
+
+        We will take 1, 2 and 3 sucessively and in place of whitespaces we will
+        concatenate the key value.
