# A robot moves in a plane starting from the original point (0,0)

#### Question:

• A robot moves in a plane starting from the original point (0,0). The robot can move UP, DOWN, LEFT, and RIGHT with a given step.
• The trace of robot movement is shown as the following:
• UP 5
• DOWN 3
• LEFT 3
• RIGHT 2

The numbers after the direction are steps. Please write a program to compute the distance from the current position after a sequence of movements and the original point. If the distance is a float, then just print the nearest integer.

#### Example:

• If the following tuples are given as input to the program:
• UP 5
• DOWN 3
• LEFT 3
• RIGHT 2
• Then, the output of the program should be: 2

#### Hints:

• In case of input data being supplied to the question, it should be assumed to be a console input.
