Answer:
Its nCr = n!/(r!.(n-r)! =n!/!!.(n-1)! = n
Explanation:
Here. the arrangement of outcome does not matters, and hence it is a combination. You should know that when arrangement matters then we have to calculate the permutation and its formula is n!/(n-r)!. However, here it is the combination, and hence its nCr or n!/r!. (n-r)!. And here r is 1 as we can have all heads or all tails. And n is n. Hence,
Its nCr = n!/(r!.(n-r)!
=n!/!!.(n-1)!
= n
Answer:
I would use variables because they store data for you and are helpful in your programs.
Answer:
void print2(int row) {
for (int i = 0; i < row; i++) {
char ch = 'a';
char print = ch;
for (int j = 0; j <= i; j++) {
cout << print++;
}
cout << endl;
}
}
int count_digits(int num) {
int count = 0;
int temp = num;
while (temp != 0) {
temp = temp / 10;
count++;
}
return (num % count);
}
