If you are not familiar with Josephus problem: There are N soldiers standing in a circle.They all get executed starting by 1 and moving by M.In the end only one of them stands alive. the code below ask for N and M and generated the last player standing. <pre><code>#include <stdio.h> #include <stdlib.h> int main() { int N, M; struct node { int player_id; struct node *next; } struct node *p, *q; int i, count; printf("Enter N (number of players): "); scanf("%d", &N); printf("Enter M (every M-th payer gets eliminated): "); scanf("%d", &M); // Create circular linked list containing all the players: p = q = malloc(sizeof(struct node)); p->player_id = 1; for (i = 2; i <= N; ++i) { p->next = malloc(sizeof(struct node)); p = p->next; p->player_id = i; } p->next = q;// Close the circular linkedlist by having the last node point to the 1st // Eliminate every M-th player as long as more than one player remains: for (count = N; count > 1; --count) { for (i = 0; i < M - 1; ++i) p = p->next; p->next = p->next->next; // Remove the eiminated player from the circular linkedl } printf("Last player left standing is %d\n.", p->player_id); return 0; } </code></pre> Lets say N=17;M=7 the output should be 13 the program above generates 2 (what happens? well it starts the counting from M not from 1 so instead of 1,8,15...... it elimintates 7,14......) This is where i need your help (as linked lists are still a difficult concept for me). How to modify this one?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
