Problem Description
A hospital is conducting a study to determine if a certain disease is related to age. To do this, they are organizing past diagnostic records and calculating the proportion of patients in the four age groups: 0-18, 19-35, 36-60, and 61 and above, relative to the total number of patients.
Input Format
The input consists of 2 lines.
The first line contains an integer \( N \) (\( 0 < N \leq 100 \)), representing the total number of patients.
The second line contains \( N \) integers, each representing the age of a patient at the time of their visit.
Output Format
The output consists of 4 lines.
The first line contains a percentage, rounded to two decimal places, representing the proportion of patients aged 0-18 relative to the total number of patients.
The second line contains a percentage, rounded to two decimal places, representing the proportion of patients aged 19-35 relative to the total number of patients.
The third line contains a percentage, rounded to two decimal places, representing the proportion of patients aged 36-60 relative to the total number of patients.
The fourth line contains a percentage, rounded to two decimal places, representing the proportion of patients aged 61 and above relative to the total number of patients.
