Do not meddle in the affairs of wizards, for they are subtle and quick to anger.
Gandalf has to work with the arcane arts regularly, to aid in his fight against Sauron. However, this can often be quite dangerous, as an arrangement of runes can have unintended consequences. He has tasked you, one of his followers, to design a system that could tell him in advance the magical outcome of a given set of runes.
The input takes the form of a series of instructions, one per line, all part of the same spell. As this is somewhat elvish magic, all of the instructions are in elvish. Gandalf has provided you with the meanings of the instructions below, so that you can better understand the magical patterns.
|arth [lbl]||region||goto [lbl]|
|pen [var1] [var2] [lbl]||less||if [var1] < [var2], goto [lbl]|
|muindor [var1] [var2] [lbl]||brother||if [var1] == [var2], goto [lbl]|
|sad [lbl]||place||label [lbl]|
|tangado [var]||to establish||declare [var] as an int, set to 0|
|ost [var1] [var2]||stronghold||declare [var1] as an int array of size [var2]|
|teithant [string]||to write||print [string] to stdout, followed by a newline|
|canad [var]||to shout||print [var] to stdout, followed by a newline|
|anno [var1] [var2]||give||var1 := var2|
|aderthad [var1] [var2]||to reunite||var1 := var1 + var2|
|adlanna [var1] [var2]||to slant||var1 := var1 / var2 (integer division)|
|adlegi [var1] [var2]||to release||var1 := var1 - var2|
|athrado [var1] [var2]||to cross||var1 := var1 * var2|
A few notes:
For example, the following spell would print out ”Hello World” (without the quotes) and exit.
teithant "Hello World" awarthad
The following spell would print out ”to Rohan!” (without the quotes) and exit.
tangado shadowfax anno shadowfax 4 aderthad shadowfax 3 pen shadowfax 6 mordor teithant "to Rohan!" awarthad sad mordor teithant "to Mordor!" awarthad
The input is a series of instructions, one per line. The instructions are terminated by a single line with the string,“END”.
For each test case, print the output of the interpreted instructions (i.e. the teithant and canad lines), with each command putting its output on its own line.
