#include <stdio.h>
#define MAX_N 10000
int a[MAX_N][MAX_N];

int main(void) {  int n, m, curr, ans;
  scanf("%d%d", &n, &m);  for (int i = 0; i < n; ++i) {    for (int j = 0; j < m; ++j) {      scanf("%d", &a[i][j]);    }  }
  ans = 0;  for (int i = 0; i < n; ++i) {    curr = 0;    for (int j = 0; j < m; ++j) {      if (a[i][j] == a[i][j + 1]) {        ++curr;      }    }    if (curr == m - 1) {      ++ans;    }  }  printf("%d\n", ans);
  return 0;}
