How can a get a sum of a loop?

Question

Need the output to look exactly like this:

Enter the upper limit: 500
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 = 511

This is what I have so far and it does not work, what should I do:

int limit, i = 1;
long sum = 1;

//Input
System.out.print("Enter the upper limit:");
limit = input.nextInt();

//Setting up the math

for(int I; i <= limit; i*=2) {
System.out.print(i+"+" = sum);

Answer 1

First of all:
welcome to Sololearn 😊
And nice question style, this is how it should be done 👍

I'm no expert in java, so I can't say much about the syntax.
But conceptionally you are on the right track :)

Some hints:
- initialize sum to 0, not to 1
- add i to sum inside the loop
- exclude to last step from the loop, to print the last number, = and the final sum

Thank you Matthias! Can you go into more details in that
