# Python Program for Frequencies of even and odd numbers in a matrix

Given a matrix of order m*n then the task is to find the frequency of even and odd numbers in matrix

Examples:

Input : m = 3, n = 3 { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } Output : Frequency of odd number = 5 Frequency of even number = 4 Input : m = 3, n = 3 { 10, 11, 12 }, { 13, 14, 15 }, { 16, 17, 18 } Output : Frequency of odd number = 4 Frequency of even number = 5

## Python3

`# Python Program to Find the frequency` `# of even and odd numbers in a matrix` ` ` `MAX` `=` `100` ` ` `# Function for calculating frequency` `def` `freq(ar, m, n):` ` ` `even ` `=` `0` ` ` `odd ` `=` `0` ` ` ` ` `for` `i ` `in` `range` `(m):` ` ` `for` `j ` `in` `range` `(n):` ` ` ` ` `# modulo by 2 to check` ` ` `# even and odd` ` ` `if` `((ar[i][j] ` `%` `2` `) ` `=` `=` `0` `):` ` ` `even ` `+` `=` `1` ` ` `else` `:` ` ` `odd ` `+` `=` `1` ` ` ` ` `# print Frequency of numbers` ` ` `print` `(` `" Frequency of odd number ="` `, odd)` ` ` `print` `(` `" Frequency of even number ="` `, even)` ` ` ` ` `# Driver code` `m ` `=` `3` `n ` `=` `3` ` ` `array ` `=` `[ [ ` `1` `, ` `2` `, ` `3` `],` ` ` `[ ` `4` `, ` `5` `, ` `6` `],` ` ` `[ ` `7` `, ` `8` `, ` `9` `] ]` ` ` `freq(array, m, n)` ` ` `# This code is contributed` `# by Anant Agarwal.` |

Output:

Frequency of odd number = 5 Frequency of even number = 4
