Why it overflowed?

[peterolson]

Sorry, it's unclear to me what you are asking. Could you explain what the purpose of the code is, and point out what exactly it's doing that is not expected?

[ying2025]

Why it appear -1058339101 in this line "235 32 -1058339101" ?

[peterolson]

I don't know exactly what you are trying to do with your code, but this line is invalid:

console.log(bigInterger(N));

Firstly, bigInterger is not spelled correctly. The function should be named bigInt.

Second, N is an array of integers. An array is not a valid argument to pass into bigInt. You can only pass in a string, a number, or another bigInt.

Since this log statement is the only place where you are using the bigInteger function, any other issues in the code are not caused by this library.
