A certain robot can perform only 4 types of movement. It can move either up or down or left or right. These movements are represented by ’U’, ’D’, ’L’, ’R’. Assume all these movements to be of unit distance. Write a function named theRoundTrip that takes all the movements the robot made in a day as input and output True of bool type if the robot returned to its starting position after its journey. Otherwise return False. If the input is bad print the message "bad input" and return to solve the next question.

Have a main function from which the answer to questions are retrieved and run the program as a whole.

Examples:
Test Case 1:
input: movement = [’U’, ’L’, ’D’, ’R’]
output: True
Explanation: In a 2D plane a unit movement up by 1, left by 1, down by 1 and right by 1 would result in arriving at the starting posistion. So we return True.

Test Case 2:
input: movement = [’U’, ’U’, ’R’, ’L’, ’D’, ’R’]
output: False
Explanation: After traversing this movement we see that we have not arrived at the start- ing position. So we return False.

Test Case 3:
input: movement = [’U’, ’U’, ’I’, ’L’, ’D’, ’R’] output: bad input

3. (6 pts) internally in the computer, with few exceptions, all numerical computation is done using binary numbers. output, however, often uses ascii, which is formed by appending 011 to the left of a bcd code. thus, an algorithm that directly converts a binary integer to a bcd integer is very useful. here is one such algorithm 1) draw lines to the left of the binary number to bound the expected bcd decades. (each decade is a group of 4 bits.) move the binary number one bit to the left. add 0011 to each bcd decade containing a binary value> 0100 repeat steps 2-3 until the last bit in the binary number has been moved into the least significant decade position. (note that when the last bit has been shifted into bcd decade, step 3 is not repeated.) read the bcd result. 2) 3) 4) 5) a) execute the algorithm for the binary number 1101101 b) execute the algorithm for the binary number 01110101110 4. (4 pts) represent the decimal number 3568 in bcd; excess-3 code; ascil; and hex.
