Consider the following algorithm tha finds a row where every entry is x in a 2-D array. Assume
that (a) the array has n rows and m columns, and that (b) the comparison on line 3 counts
towards the running time.
01 FOR every row in the array
FOR every column in the array
IF [row] [column]
02
03
'x' THEN
04
IF column is the last THEN
05
DISPLAY found row
06
ENDIF
07
ELSE
08
move on to the next row
09
ENDIF
