How to find the maximum number of characters between any two same character in a string with C

Answer 1

#include <stdio.h>
#include <math.h>

int GetMaxChars(char str[]) {
    int size = strlen(str);
    int maxCh = 0;

    for (int i = 0; i < size - 1; i++)
        for (int j = i + 1; j < size; j++)
            if (str[i] == str[j]) {
                int temp = abs(j - i - 1);
                maxCh = maxCh > temp ? maxCh : temp;
            }
    return maxCh;
}

int main() {
    char str[] = "aBcaaBdefBgh";

    printf("%d", GetMaxChars(str));

    return 0;
}
