Answer:
n! = n*(n-1)*(n-2)*(n-3)* ... *2*1
Explanation:
The factorial operator is simply a mathematical expression of the product of a stated integer and all integers below that number down to 1. Consider these following examples:
4! = 4 * 3 * 2 * 1
4! = 12 * 2 * 1
4! = 24
6! = 6 * 5 * 4 * 3 * 2 * 1
6! = 30 * 4 * 3 * 2 * 1
6! = 120 * 3 * 2 * 1
6! = 360 * 2 * 1
6! = 720
So, the factorial of n would follow the same as such:
n! = n * (n-1) * (n-2) * ... * 2 * 1
Cheers.
Answer:
3. alpha = {1, 5, 6, 7, 5}
Explanation:
Initially, we have that:
alpha[0] = 1;
alpha[1] = 2;
alpha[2] = 3;
alpha[3] = 4;
alpha[4] = 5;
For j higher than 2, we have that:
alpha[j - 1] = alpha[j] + 2;
So
j = 3
a[2] = alpha[3]+2 = 4 + 2 = 6;
j = 4
a[3] = alpha[4]+2 = 5+2 = 7;
The correct answer is:
3. alpha = {1, 5, 6, 7, 5}
Unicode was invented to create a "universal text", or a language framework that any computer or device could understand.
