Hello, Shaul Salomon.
. . .
Could you please double-check the consistency of your test 7 with the problem statement? The problem statement specifies that "[...] when the number 0 is generated. This number is not considered for the mean." . . .

In test 7, I get only one random number value, which is zero, and this should be discarded. Therefore the set of numbers to average is an empty set: this empty set has a sum of zero (or undefined?) and — most importantly — a count of zero. So therefore the mean there should be undefined, or NaN, as far as I can understand. This is how I implemented Solution 1391527. Please let me know if I am overlooking some important point. . . . —Thanks, David.
