i'm really upset that i've never thought of this

Oh.. God.. I see very clever solution and relize that i'm stupid..
I'm going to drown myself by stuffing myhead into toilet

Extra Package is good but not

Im new with the programming, just want to now if i understand this correctly, getNumericValue is checking for the first char from the string and return string depending on the number?

I'm not sure why people are voting this as best practices. You're completely right as to why this answer is not optimal.

That's awesome, i tried to do it this way, but i had errors that "Arrays" was not found. By this example now i see how to do imports. Thank you :)

I should have used an Anonymous Array!

若测试用例有2位数字的话，这个答案就不适用了

is not that obsolete since i got similar code, but I failed tests that have 2 digits.

This is exactly what I did but it did not work for some reason and i mean literally exactly

It's clever, but not the best practice.

• Poor performance: O(n*logN) vs O(n).
• Input array data reordered. Users won't expect this from minMax function.

This function needed to return an int array. One way to do this was to build a new array and add the min and max to it and then return. But here you are doing it in one step without giving the array a variable name. You create a new int[] and initialize it all in one line.

what does new do

the shortest code
but not very efficient. O(N Log N)
