+Problem Description :
+The Binary number system only uses two digits, 0 and 1 and number system can be called binary string. You are required to implement the following function:
+
+int OperationsBinaryString(char* str);
+
+The function accepts a string str as its argument. The string str consists of binary digits eparated with an alphabet as follows:
+
+– A denotes AND operation
+– B denotes OR operation
+– C denotes XOR Operation
+You are required to calculate the result of the string str, scanning the string to right taking one opearation at a time, and return the same.
+
+Note:
+
+No order of priorities of operations is required
+Length of str is odd
+If str is NULL or None (in case of Python), return -1
+Input:
+str: 1C0C1C1A0B1
+
+Output:
+1
