Bigger Is Greater Hackerrank Solution C -

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" .

// Step 1: Find the pivot for (i = n - 2; i >= 0; i--) if (str[i] < str[i + 1]) break;

void reverse(char *str, int start, int end) while (start < end) swap(&str[start], &str[end]); start++; end--; bigger is greater hackerrank solution c

if (i < 0) printf("no answer\n"); return;

printf("%s\n", str);

// Step 4: Reverse the suffix after pivot reverse(str, i + 1, n - 1);

// Step 3: Swap pivot with that character swap(&str[i], &str[j]); Here’s a structured report on solving the HackerRank

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