The NaN in NaNo was a dead giveaway.

The obvious way to push NaN would be to divide 0 by itself, 2\I pushes the input length (0) twice, / performs division, and N prints a float.

We're left with printing o, and 'o' is a string literal that O prints.

Whatever characters were left had to belong to the other program. In fact, a pushes a linefeed, 5F the factorial of 5 (120), \a turns that into 120 linefeeds, and Z prints the entire stack.
