There is a set of numbers, how to determine that they end with a certain number?

Question

Algorithms

for example there are some numbers: 54, 3, 25, 47 find out which one ends with 4

Answer 1

arr.filter(n => n % 10 === 4)
or or or
arr.filter(n => /4$/.test(n))
arr.filter(n => ''.endsWith.call(n, 4))
(`${arr}`.match(/\d*4(?=\D)/g) || []).map(Number)

Answer 2

int n = 4;
int numbers[n] = {54, 3, 25, 47};
for (int i = 0; i < n; i++) {
    if (numbers[i] % 10 == 4) {
        cout << numbers[i] << endl; 
    }
}
