Return False if len(stack) != 1 else int(stack)Ģ. Sliding Window Maximum (Leetcode Number: 239)ģ. Top K Frequent Elements (Leetcode Number: 347)īy applying the heap queue, the smallest value could always be removed first. For example CT scan images are routinely int16 values, -32768 to +32767. The design runs at a frequency of 36.3 MHz on Virtex-5 Xilinx FPGA. If tokens != "+" and tokens != "-" and tokens != "/" and tokens != "*": Can someone please post a simple matlab code for image encryption/decryption. The module is verified through comparing the result with that obtained from MATLAB tools. eval(f'')ĭef evalRPN(self, tokens: List) -> int: Be aware of the sequence of those two elements extracted from the stack is （ the second last operand in the stack)(operator)(last operand in the stack) -> append the result to the stackįor Python, the following function could be used to simplify the codes. Evaluate Reverse Polish Notation (Leetcode Number: 150)Ĭopy the element to the stack if it's operand -> complete the arithmetic operation of the last element and the second last element in the stack when the element of the original list is detected to be an operator. The RSA Encryption Scheme is often used to encrypt and then decrypt electronic communications.
