# The power of thor #BUG #PHP

with the php language at the third testcase is a bug, with the code below I solve the first and second testcase, but the third and fourth is impossible, my variable “torX” is increasing in one turn from 4 to 17 for the third level, and for the fourth the programm doesn’t change direction, it goes in the opposit direction:

``````    <?php
fscanf(STDIN, "%d %d %d %d",
\$lightX, // the X position of the light of power
\$lightY, // the Y position of the light of power
\$initialTX, // Thor's starting X position
\$initialTY // Thor's starting Y position
);

\$torX = \$initialTX;
\$torY = \$initialTY;
\$turn = 0;
\$s = 0;
\$n = 0;
while (TRUE)
{
\$turn++;
\$x = "";
\$y = "";

if(\$torX < \$lightX){
\$x = "E";
\$torX = \$torX + 1;
}elseif(\$torX > \$lightX){
\$x = "W";
\$torX = \$torX - 1;
}

if(\$torY < \$lightY){
\$y = "S";
\$torY += \$torY + 1;
\$s = \$s + 1;
}elseif(\$torY > \$lightY){
\$y = "N";
\$torY = \$torY - 1;
\$n = \$n + 1;
}

if(\$turn < 13 && \$torY == 17){
\$torY -= \$turn;
}

echo(\$y.\$x."\n");
error_log(var_export(\$torY, true));
}
``````

and the ouput:

`Standard Error Stream: 9 19 18 13 27 26 25 24 23 22 21 20 19 18 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 ...`
