Successful Pairs of Spells and Potions

Medium

You receive two positive integer arrays spells and potions , of length n and m respectively, where spells[i] represents the strength of the i^th spell and potions[j] represents the strength of the j^th potion.

You are also given an integer success . A spell and potion pair is considered successful if the product of their strengths is at least success .

Produce an integer array pairs of length n where pairs[i] is the number of potions that will form a successful pair with the i^th spell.

Example 1

Input: spells = [5,1,3], potions = [1,2,3,4,5], success = 7

Output: [4,0,3]

Explanation:

  • 0th spell: 5 * [1,2,3,4,5] = [5, 10, 15, 20, 25]. 4 pairs are successful.

  • 1st spell: 1 * [1,2,3,4,5] = [1,2,3,4,5]. 0 pairs are successful.

  • 2nd spell: 3 * [1,2,3,4,5] = [3,6, 9, 12, 15]. 3 pairs are successful.

Thus, [4,0,3] is returned.

Example 2

Input: spells = [3,1,2], potions = [8,5,8], success = 16

Output: [2,0,2]

Explanation:

  • 0th spell: 3 * [8,5,8] = [ 24,15, 24]. 2 pairs are successful.

  • 1st spell: 1 * [8,5,8] = [8,5,8]. 0 pairs are successful.

  • 2nd spell: 2 * [8,5,8] = [ 16,10, 16]. 2 pairs are successful.

Thus, [2,0,2] is returned.

Constraints

  • n == spells.length
  • m == potions.length
  • 1 <= n, m <= 10^5
  • 1 <= spells[i], potions[i] <= 10^5
  • 1 <= success <= 10^10
