Bug Report for https://neetcode.io/problems/permutation-string
Please describe the bug below and include any steps to reproduce the bug or screenshots if possible.
I gave this function: private void permute(String prefix, String str, Set permutations) {
int n = str.length();
if (n == 0) {
permutations.add(prefix);
} else {
for (int i = 0; i < n; i++) {
permute(prefix + str.charAt(i),
str.substring(0, i) + str.substring(i + 1, n),
permutations);
}
}
}
and the error below came:
Runtime Error (NZEC)
Passed test cases: 5 / 26
stderr
run.sh: line 1: 3 Killed /usr/local/jdk17/bin/java --module-path /usr/local/javafx-sdk-22.0.2/lib --add-modules javafx.web,javafx.fxml,javafx.swing,javafx.controls,javafx.media,javafx.base,javafx.graphics Main
If you're getting a Runtime Error (NZEC) and the program is being killed, it's likely due to memory constraints or stack overflow with larger inputs.
