As I mentioned elsewhere, the learning curve for Hacked is probably a bit steep for new coders. I didn’t just want to give you the answers outright. I’ve included hints to help where you might get stuck, all wrapped in spoiler tags. Teach a man (or woman) to fish! I’ve also included comments in the code blocks, which you can’t do in the app, but may help those who are just starting out with coding. Ignore them when typing them into the hackpad.
Note that while I tend to use the keyword “return” for better readability/understanding, you don’t always need it when the final action is to output your answer, which will save you some keystrokes and score you more points.

Here is my solution for Where is Waldo
[hack]
var_a = "";
while var_b < input.length – 4 {
while var_c < 5 {
var_a = var_a + input[var_b + var_c];
var_c++;
}
if var_a == "waldo" {
return var_b;
}
var_b++;
var_c=0;
var_a="";
}
[/hack]
Here’s my Where’s Waldo code:
[hack]
var_a = "waldo";
var_b = input;
while var_c < var_b.length {
var_d = true;
var_e = 0;
while var_e < var_a.length {
if var_b[var_c + var_e] != var_a[var_e] {
var_d = false;
}
var_e++;
}
if var_d {
return var_c;
}
var_c++;
}[/hack]
While var_a < input.lenght -1 {
If input [ var_a] == "w" {
If input [ var_a + 1] == "a" && input [ var_a + 2] == "l" && input [ var_a +3] == "d" && input [ var_a +4 ] == "o" {
Var_b= var_a;
}
}
}
While var_a < input.lenght -1 {
If input [ var_a] == "w" {
If input [ var_a + 1] == "a" && input [ var_a + 2] == "l" && input [ var_a +3] == "d" && input [ var_a +4 ] == "o" {
Var_b= var_a;
}
}
Var_a++;
}
Return var_b;
What is the meaning “<” and “"” and how can i type them in in the app? I have already solved this but i want tó try out different solutions
Somewhere down the line the code got mangled and converted into html elements. They should have been < and > and ” symbols
Your code for “Count Words” breaks if I pass it an empty string. I know that’s not one of the test data, but still, consider this:
var_o = 0;
if input.length > 0 {
var_o++;
while var_c < input.length {
if input[var_c] == " " {
var_o++;
}
var_c++;
}
}
var_o;
