MAXSUMSQ - Maximum Sum Sequences |
Given an array A having n elements, let X be the maximum sum of any contiguous sequence in the array. How many contiguous sequences in A sum up to X?
Input
The first line contains T the number of test cases. There follow 2T lines, 2 for each test case. The first line contains the n, the number of elements in the array. The second line contains n space separated integers Ai.
Output
Output T lines, one for each test case. On each line, output two space separated integers; the maximum sequence sum, and the number of sequences which obtain this maximum sum.
Example
Input: 2
3
-1 -1 -1
4
2 0 -2 2 Output: -1 3
2 4
Constraints
1 <= T <= 35
1 <= n <= 100000
-1000 <= Ai <= 1000

AC with map easily Last edit: 2023-03-12 05:08:51 |

did it with BIT how to do it in O(N) though |

Some points: 1) use scanf and printf, I got TLE with cin, cout even with fastio. 2)if you are using map, use unordered_map instead. |

Can anyone have a look at my code for this problem and tell what is wrong?? <snip> Last edit: 2022-06-28 22:07:39 |

use kadane's algo along with count array |

Finally AC after 4 WA and 2 TLE. |

accepted using scanf and printf got tle using cin and cout |

map -> TLE unordered_map -> AC |

Use long long for "the number of sequences which obtains this maximum sum". The constraints of the problem allow this 'max_count' field to be > (n/2)^2, where n is 10^5 Thanks @Ankit Sultana! |

@reddragon the first element only, the first and the second, the last element only, the whole array |
