3. You have been contracted to design a system for a smart car. The company installed four laser radars on the car’s corners to use as sensors, for the car to be able to avoid collisions at the rear, and the front. a. Using a flowchart, show the algorithm for the car collision avoidance system.
b. Using any recommended programming language of your choice, write a source code for the car collision avoidance system.

*write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard).
