Find max in struct array

Given a struct array of type Height, find max

struct Height{
  int feet;
  int inches;
}

Question source : Microsoft Interview Experience Set 127 | (On-Campus for IDC)

The idea is simple, traverse the array, and keep track of max value 
value of array element(in inches) = 12*feet + inches 

Implementation:

CPP

// CPP program to return max
// in struct array
#include <iostream>
#include <climits>
using namespace std;

// struct Height
// 1 feet = 12 inches
struct Height {
    int feet;
    int inches;
};

// return max of the array
int findMax(Height arr[], int n)
{
    int mx = INT_MIN;
    for (int i = 0; i < n; i++) {
        int temp = 12 * (arr[i].feet)
                    + arr[i].inches;
        mx = max(mx, temp);
    }
    return mx;
}

// driver program
int main()
{
    // initialize the array
    Height arr[] = {
        { 1, 3 },
        { 10, 5 },
        { 6, 8 },
        { 3, 7 },
        { 5, 9 }
    };
    int res = findMax(arr, 5);
    cout << "max :: " << res << endl;
    return 0;
}

Python3

# Python program to return max
# in list of dictionaries

# Importing the sys module for INT_MIN
import sys

# Dictionary to represent Height
# 1 feet = 12 inches
class Height:
    def __init__(self, feet, inches):
        self.feet = feet
        self.inches = inches

# Function to return max of the list
def findMax(arr):
    mx = -sys.maxsize - 1
    for i in arr:
        temp = 12 * i['feet'] + i['inches']
        mx = max(mx, temp)
    return mx

# Driver program
if __name__ == "__main__":
    # Initialize the list
    arr = [
        {'feet': 1, 'inches': 3},
        {'feet': 10, 'inches': 5},
        {'feet': 6, 'inches': 8},
        {'feet': 3, 'inches': 7},
        {'feet': 5, 'inches': 9}
    ]
    res = findMax(arr)
    print("max ::", res)

Output

max :: 125
