The problem is that Im trying to get rid of a gap in the output(at bottom) but to do so I need to get rid of the first endl under the case'W' but if I do that the output will get worse.
At the bottom I'll put the output I'm trying to get, the output I'm getting, and the output I'll get if i get rid of the endl.
The inputs are:
S B U U W R R W D D W D D W M T R T
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105

CORRECT OUTPUT:
STARTED AT POSITION (0,0)
BAD COMMAND 'B' IGNORED.
UP UP
POS = (0,2)
RIGHT RIGHT
POS = (2,2)
DOWN DOWN
POS = (2,0)
DOWN BAD MOVE TO (2,-1)
DOWN BAD MOVE TO (2,-1)
POS = (2,0)
BAD COMMAND 'B' IGNORED.
TERMINATED AT POSITION (2,0)
CURRENT OUTPUT:
STARTED AT POSITION (0,0)
BAD COMMAND 'B' IGNORED.
UP UP
POS = (0,2)
RIGHT RIGHT
POS = (2,2)
DOWN DOWN
POS = (2,0)
DOWN BAD MOVE TO (2,-1)
DOWN BAD MOVE TO (2,-1)
// trying to get rid of this gap
POS = (2,0)
BAD COMMAND 'M' IGNORED.
TERMINATED AT POSITION (2,0)
OUTPUT WITHOUT the endl:
STARTED AT POSITION (0,0)
BAD COMMAND 'B' IGNORED.
UP UP POS = (0,2)
RIGHT RIGHT POS = (2,2)
DOWN DOWN POS = (2,0)
DOWN BAD MOVE TO (2,-1)
DOWN BAD MOVE TO (2,-1)
POS = (2,0)
BAD COMMAND 'M' IGNORED.
TERMINATED AT POSITION (2,0)
