sorting numbers from a .txt doc into different category with if statements and loops


sorting numbers from a .txt doc into different category with if statements and loops

fixed the issue. Will look into that further You need to use the AND (&&) operator instead of the OR (||) operator within the conditions for your IF statements, for example:
code :
if((cardNumber.length() > 15) && (cardNumber.length() < 18)) {
    // Do whatever .................
}

I wish did fix the issue. For z to be a prime number, it must be the case that there does not exist any number a such that 2 <= a <= sqrt(z) and a is a factor of z. I'd change your code to:
code :
import math
y=1
z=y
while z>= 1 and z<1000 :
    z= 2*y + 1
    y=y+1
    if all(z%a != 0 for a in range (2,int(math.sqrt(z) + 1))):
        print(z)

wish of those help No need for a (nested) loop, use the vectorised ifelse instead:
code :
testing = ifelse(testing > 1, 'More', ifelse(testing < -1, 'Less', 'Same'))

around this issue You have an Array notprim that you can imagine as [undefined × 100], and !!undefined === false, i.e. undefined is falsy
If for some number n you have notprim[n] falsy, you assume it means n must be a prime number and add it to another Array, prim
code :
for (t = 0; t <= 100; t = t + n)
    // t ∈ nℤ, 0 <= t <= 100

I wish this help you
The problem is it prints out "guess higher" but the computer does not always guess higher. I'm not sure how to go about this problem.

like below fixes the issue I want to write a program that makes the user enter 3 integers num1,num2,num3 and give me the sum of the even numbers entered and the average of the even numbers without using if statements/loop/arrays I'm stuck can't figure it out. , You could use streams and filter() like
code :
int num1 = 2, num2 = 3, num3 = 4;
int sum = IntStream.of(num1, num2, num3).filter(x -> x % 2 == 0).sum();
double count = IntStream.of(num1, num2, num3).filter(x -> x % 2 == 0).count();
System.out.printf("sum of evens is %d and the average is %.2f%n", sum, sum / count);
int sum = (num1 % 2 == 0 ? num1 : 0) 
        + (num2 % 2 == 0 ? num2 : 0) + (num3 % 2 == 0 ? num3 : 0);
double count = (num1 % 2 == 0 ? 1 : 0) 
        + (num2 % 2 == 0 ? 1 : 0) + (num3 % 2 == 0 ? 1 : 0);
