| 5 | +字符串处理问题,需要考虑 `万亿`, `十万` 等情况。 |

| 7 | +```go |
| 8 | +package main |

| 10 | +import "fmt" |
| 11 | + |
| 12 | +func main() { |
| 13 | + fmt.Println(solution("二百")) |
| 14 | +} |
| 15 | + |
| 16 | +func solution(chineseNum string) int { |
| 17 | + res, part, temp := 0, 0, 0 |
| 18 | + numberDict := map[string]int{"零": 0, "一": 1, "二": 2, "三": 3, "四": 4, "五": 5, "六": 6, "七": 7, "八": 8, "九": 9} |
| 19 | + unitDict := map[string]int{"十": 10, "百": 100, "千": 1000} |
| 20 | + largeUnitDict := map[string]int{"万": 10000} // "十万" |
| 21 | + largerUnitDict := map[string]int{"亿": 100000000} // "万亿" |
| 22 | + for _, ch := range chineseNum { |
| 23 | + if val, ok := numberDict[string(ch)]; ok { |
| 24 | + temp = val |
| 25 | + } else if val, ok := unitDict[string(ch)]; ok { |
| 26 | + part += temp * val |
| 27 | + temp = 0 |
| 28 | + } else if val, ok := largeUnitDict[string(ch)]; ok { |
| 29 | + part += temp |
| 30 | + temp = 0 |

| 35 | + part *= val |
| 36 | + res += part // 亿之前的数直接加到 res 里 |
| 37 | + part = 0 |
| 38 | + } |
| 39 | + |
| 40 | + } |
| 41 | + res += part + temp |
