Python: Find a number in a given matrix which is maximum in its column and minimum in its row

Python Basic - 1: Exercise-104 with Solution

Write a Python program to find a number in a given matrix that is maximum in its column and minimum in its row.

Sample Solution:

Python Code:

# Number in a Matrix: Maximum in its column and minimum in its row.
def matrix_number(matrix):
   result = set(map(min, matrix)) & set(map(max, zip(*matrix)))
   return list(result)
m1 = [[1,2], [2,3]]
print("Original matrix:",m1)
print("Number in the said matrix which is maximum in its column and minimum in its row:")
print(matrix_number(m1))
m1 = [[1,2,3], [3,4,5]]
print("\nOriginal matrix:",m1)
print("Number in the said matrix which is maximum in its column and minimum in its row:")
print(matrix_number(m1))
m1 = [[7,5,6], [3,4,4], [6,5,7]]
print("\nOriginal matrix:",m1)
print("Number in the said matrix which is maximum in its column and minimum in its row:")
print(matrix_number(m1))

Sample Output:

Original matrix: [[1, 2], [2, 3]]
Number in the said matrix which is maximum in its column and minimum in its row:
[2]

Original matrix: [[1, 2, 3], [3, 4, 5]]
Number in the said matrix which is maximum in its column and minimum in its row:
[3]

Original matrix: [[7, 5, 6], [3, 4, 4], [6, 5, 7]]
Number in the said matrix which is maximum in its column and minimum in its row:
[5]
