In this HackerRank Functions in PYTHON problem solution,

min

 

The tool min returns the minimum value along a given axis.

 

import numpy

my_array = numpy.array([[2, 5], 
                        [3, 7],
                        [1, 3],
                        [4, 0]])

print numpy.min(my_array, axis = 0)         #Output : [1 0]
print numpy.min(my_array, axis = 1)         #Output : [2 3 1 0]
print numpy.min(my_array, axis = None)      #Output : 0
print numpy.min(my_array)                   #Output : 0

 

By default, the axis value is None. Therefore, it finds the minimum over all the dimensions of the input array.

 

max

 

The tool max returns the maximum value along a given axis.

 

import numpy

my_array = numpy.array([[2, 5], 
                        [3, 7],
                        [1, 3],
                        [4, 0]])

print numpy.max(my_array, axis = 0)         #Output : [4 7]
print numpy.max(my_array, axis = 1)         #Output : [5 7 3 4]
print numpy.max(my_array, axis = None)      #Output : 7
print numpy.max(my_array)                   #Output : 7

 

By default, the axis value is None. Therefore, it finds the maximum over all the dimensions of the input array.

 


 

Task

You are given a 2-D array with dimensions N * M .

Your task is to perform the min function over axis 1 and then find the max of that.

Input Format

The first line of input contains the space separated values of N and M.

The next N lines contains M space separated integers.

Output Format

Compute the min along axis 1 and then print the max of that result.

Sample Input

4 2
2 5
3 7
1 3
4 0

Sample Output

3

Explanation

The min along axis 1 = [2,3,1,0]

The max of [2,3,1,0] = 3
