游游的最长稳定子数组

从第二个元素开始遍历数组,如果当前元素和前一个元素之差的绝对值不超过1,则当前稳定子数组的长度加1,否则,重置当前稳定子数组的长度为1,然后维护一个最大的答案即可
#include <bits/stdc++.h>
using namespace std;
#define int long long
const int N = 2e5 + 5;
int __t = 1, n, a[N];
void solve() {
cin >> n;
int sum = 1, ans = 1;
for (int i = 1; i <= n; i++)
cin >> a[i];
for (int i = 2; i <= n; i++) {
if (abs(a[i] - a[i - 1]) <= 1)
sum++;
else
sum = 1;
ans = max(ans, sum);
}
cout << ans << '\n';
return;
}
int32_t main() {
#ifdef ONLINE_JUDGE
ios::sync_with_stdio(false);
cin.tie(0);
#endif
// cin >> __t;
while (__t--)
solve();
return 0;
}
