Define class Palace – Visit Status

N persons visit a palace. The name, gender(M-Male or F-Female) and age of the N persons are passed as the input. The program must find the number of males and number of females visited the palace in each age. For each age (ascending order), the program must print the age, the number of males, the number of females and the names of the persons. In each age group, the names of the persons must be printed in the order of their occurrence.

Your task is to define the class Palace so that the program runs successfully.

Example Input/Output 1:
Input:
7
Hector M 25
Arun M 25
Lavanya F 25
Oliver M 22
Catherine F 24
Jhanvi F 23
Kavin M 23

Output:
22 1 0
Oliver
23 1 1
Jhanvi Kavin
24 0 1
Catherine
25 2 1
Hector Arun Lavanya

Explanation:
Here N = 7.
Age 22: 1 male 0 females (Oliver).
Age 23: 1 male 1 female (Jhanvi, Kavin).
Age 24: 0 males 1 female (Catherine).
Age 25: 2 males 1 female (Hector, Arun, Lavanya).
