I have an array called @remaining and a string called $righteq. I want to store any functions that are not + and -signs into the array. Also, the function e^(t plus or minus a number), otherwise known as "e\^\(t[\+-](\d+\.?\d*|\.\d+)\)" is a special case. I want to detect such a special case, and store it into the array. 
$righteq examples:
+++-+++t^n+++f^n+e^(t-123.22)
or
t^n+--++-+f^n++e^(t-123.22)++
or
+++++---+t^n+f^n+++e^(t-123.22)-

After processing $righteq, the array looks like this: 
$remaining[0] is "t^n"
$remaining[1] is "f^n"
$remaining[2] is "e^(t-123.22)"
