# KiloMan

**Timelimit: 1**

By TopCoder* USA

You've reached one of the last bosses in the new hit 2-D side-scrolling action game, KiloMan. The boss has a large gun that can shoot projectiles at various heights. For each shot, KiloMan can either stand still or jump. If he stands still and the shot is at height 1 or 2, then he gets hit. If he jumps and the shot is at a height above 2, then he is also hit. Otherwise, he is not hit. Given the height of each shot and a sequence of jumps, how many hits will KiloMan take?

The input contains several test cases. The first line of
input contain an integer **N** that indicates the
number of test cases. Each test case is composed by three lines and starts with a line
containing the number of shots **S** (1 ≤ **S** ≤ 50).
The second line contains **S** integers,
that represent the pattern of heights at which the
shots are being fired. Each element of pattern will be between
1 and 7, inclusive. The third line of input contains the string
'jumps', that represents the sequence of jumps that KiloMan
will attempt; 'J' means he will jump and 'S' means he will
stand still. For example, if the first number of the pattern is
3 and the first character of jumps is 'J', then KiloMan will
jump right as a shot is fired at height 3 (and thus he will be
hit).

For each case, your program should print an integer representing the number of times KiloMan is hit.
