I can’t find an error in the Java code

Tags: Mobile, Software

I wrote the source code for a new application on IOS, when writing there were no errors, but when I ran the code, an error appeared in this place:
Code:
var t = readLine()!
var s = readLine()!
var len_s = s.count
var t_lis = Set(t)
var c_s = Counter(s)
var c_t = Counter(t_lis[len_s])
var c_res = [String: String]()
var summ = 0
for e in c_s{
c_res[e] = [c_s[e], min( c_s[e], c_t[e] )]
summ += c_res[e][1]}
for i in (t.count-s.count) + 1 {
if summ == len_s-1{
print(i)
break

}
if t[i] in c_res
if c_res[t[i]][1] > 0{
c_res[t[i]][1] -= 1
summ -= 1
}
if i+len_s < t.count && t[i+len_s] in c_res
if c_res[ t[i+len_s] ][1] < c_res[ t[i+len_s] ][0]{
c_res[ t[i+len_s] ][1] += 1
summ += 1

}
else
print(-1)
}
Who can tell what is wrong?

This doesn’t look like a full Java method, so it’s quite understandable the Java interpreter gives an error. Then it’s up to you to fix it.

May I remark that print(-1) doesn’t make much sense in an iOS app?

The error is likely due to the fact that you are attempting to access elements in an array that do not exist. In the code, you are accessing elements in the array t_lis with the index len_s. However, since len_s is the length of the string s, it will be larger than the length of t_lis, which will result in an out of bounds error. To fix this, change the line of code to access the last element in t_lis instead of using the index len_s.

Java Code Error Solution

In reply to I can’t find an error in the Java code

It seems like the error is due to a syntax issue in the following line:

css
Copy code
c_res[e] = [c_s[e], min( c_s[e], c_t[e] )]
The issue is that the square brackets [] are being used to create a list, but the type of c_res[e] is a dictionary. To fix this issue, you can change the square brackets to regular parentheses to create a tuple instead, like this:

css
Copy code
c_res[e] = (c_s[e], min( c_s[e], c_t[e] ))
In addition to this, there are a few other things that you may want to consider:

1- The loop condition for i in (t.count-s.count) + 1 may not be what you intended. It will only loop once if t.count-s.count is equal to zero, and it will loop one time too many if t.count-s.count is greater than one. You may want to revise this condition to ensure that it loops over the correct range.

2- The if statements that check if t[i] in c_res and t[i+len_s] in c_res are missing colons at the end. You should add colons to the end of these statements to make them syntactically correct.
