+This is the code to build suffix array for any given string input.
+
+Suffix Array:-
+A suffix array for a given string is basically a sorted array of all suffixes of a string.
+
+For example:-
+
+Given the string is "banana"
+
+The suffixes are:-
+
+0 banana			5 a
+1 anana          sorted		3 ana
+2 nana       -------------->	1 anana
+3 ana	      alpabetically	0 banana
+4 na				4 na 
+5 a				2 nana
+
+So, the suffix array for the string "banana" will be [5,3,1,0,4,2]
+
+Application of suffix array:-
+
+Suffix array is an extremely useful data structure, it can be used for a wide range of problems. Following are some famous problems where Suffix array can be used.
+1) Pattern Searching
+2) Finding the longest repeated substring
+3) Finding the longest common substring
+4) Finding the longest palindrome in a string
