WHY

以前我也碰到过，印象中是这样？

@echo off & setlocal enabledelayedexpansion
set /a min=0, result=0
for %%i in (-2, 1, -3, 4, -1, 2, 1, -5, 4) do (
    set /a sum+=%%i, tmpSum=sum-min
    if !result! LSS !tmpSum! set "result=!tmpSum!"
    if !min! GTR !sum! set "min=!sum!"
)
if !result! LSS 0 set "result=0"
echo;!result!
pause
