[PE-D][Tester D] Negative past transaction count

[soc-pe-bot]

I tried to keep adding transaction to the limit and eventually it became negative. I assume you are using int here thats why when it hit the max value of int, it became negative.

Suggestion: It is good to limit the max transaction count.

@seriouslia0 your sum needs to check that the total is less than Long.MAX_VALUE

I already changed to long type and limit the increment to take in number less than the max value
