寫一個?function?產出兩個結果

1.顯示20~30,31~40,41~50?各年齡層的人數與性別以及平均薪資
ex:
20~30:2,male:1,female:1,average?salary:22,000
31~40:2,male:1,female:1,average?salary:32,000
...

2.把第一題的結果組成二維陣列並用上方的print方式顯示出來
ex:
Array
(
????[20~30]?=>?Array
????????(
????????????[member]?=>?2
????????????[male]?=>?1
????????????[female]?=>?1
????????????[average?salary]?=>?22,000
????????)

????[31~40]?=>?Array
????????(
????????????[member]?=>?2
????????????[male]?=>?1
????????????[female]?=>?1
????????????[average?salary]?=>?32,000
????????)

????...
