MWC '15 #4 P3: Salt
View as PDFAfter failing his accounting, physics and engineering tests all in one day, has decided to give you a problem! The problem is as follows.
There are grains of salt, labelled
to
. The
th grain is located at the coordinate
. Two grains won't occupy the same coordinate (because that's crazy!).
You are to answer queries. There are two types of queries.
1 x y– if there is a piece of salt atoutput
salty, otherwise outputbland.2 X x– output the number of pieces of salt with an x-coordinate of.
2 Y y– output the number of pieces of salt with a y-coordinate of.
Input Specification
Input will initiate with two space separated integers and
on a single line.
lines follow with two space separated integers,
and
, the coordinate of the
th grain of salt.
lines follow, in the queries form explained above.
Note: fast input may be required.
Constraints
Subtask 1 [10%]
Subtask 2 [30%]
Subtask 3 [60%]
Output Specification
lines, one for each query.
