Bigger Is Greater: Hackerrank Solution C

void reverse(char *str, int start, int end) while (start < end) swap(&str[start], &str[end]); start++; end--;

int main() int t; scanf("%d", &t);

Here’s a structured report on solving the HackerRank problem using C . Problem Statement Given a word (string of lowercase English letters), find the lexicographically smallest greater permutation of its characters. If no such permutation exists (i.e., the string is already the largest possible), return "no answer" . bigger is greater hackerrank solution c

// Step 4: Reverse the suffix after pivot reverse(str, i + 1, n - 1); void reverse(char *str, int start, int end) while

// Step 3: Swap pivot with that character swap(&str[i], &str[j]); void reverse(char *str
