Check if Point Is Reachable solution leetcode – There exists an infinitely large grid. You are currently at point (1, 1), and you need to reach the point (targetX, targetY) using a finite number of steps.

Check if Point Is Reachable solution leetcode

In one step, you can move from point (x, y) to any one of the following points:

  • (x, y - x)
  • (x - y, y)
  • (2 * x, y)
  • (x, 2 * y)

Given two integers targetX and targetY representing the X-coordinate and Y-coordinate of your final position, return true if you can reach the point from (1, 1) using some number of steps, and false otherwise.

 

Check if Point Is Reachable solution leetcode

Input: targetX = 6, targetY = 9
Output: false
Explanation: It is impossible to reach (6,9) from (1,1) using any sequence of moves, so false is returned.

Example 2:

Input: targetX = 4, targetY = 7
Output: true
Explanation: You can follow the path (1,1) -> (1,2) -> (1,4) -> (1,8) -> (1,7) -> (2,7) -> (4,7).

 

Constraints:

  • 1 <= targetX, targetY <= 109

Maximum Subsequence Score solution leetcode – You are given two 0-indexed integer arrays nums1 and nums2 of equal length n and a positive integer k. You must choose a subsequence of indices from nums1 of length k.

Maximum Subsequence Score solution leetcode

For chosen indices i0, i1, …, ik - 1, your score is defined as:

  • The sum of the selected elements from nums1 multiplied with the minimum of the selected elements from nums2.
  • It can defined simply as: (nums1[i0] + nums1[i1] +...+ nums1[ik - 1]) * min(nums2[i0] , nums2[i1], ... ,nums2[ik - 1]).

Return the maximum possible score.

A subsequence of indices of an array is a set that can be derived from the set {0, 1, ..., n-1} by deleting some or no elements.

 

Maximum Subsequence Score solution leetcode

Input: nums1 = [1,3,3,2], nums2 = [2,1,3,4], k = 3
Output: 12
Explanation: 
The four possible subsequence scores are:
- We choose the indices 0, 1, and 2 with score = (1+3+3) * min(2,1,3) = 7.
- We choose the indices 0, 1, and 3 with score = (1+3+2) * min(2,1,4) = 6. 
- We choose the indices 0, 2, and 3 with score = (1+3+2) * min(2,3,4) = 12. 
- We choose the indices 1, 2, and 3 with score = (3+3+2) * min(1,3,4) = 8.
Therefore, we return the max score, which is 12.

Maximum Subsequence Score solution leetcode

Input: nums1 = [4,2,3,1,1], nums2 = [7,5,10,9,6], k = 1
Output: 30
Explanation: 
Choosing index 2 is optimal: nums1[2] * nums2[2] = 3 * 10 = 30 is the maximum possible score.

 

Constraints:

  • n == nums1.length == nums2.length
  • 1 <= n <= 105
  • 0 <= nums1[i], nums2[j] <= 105
  • 1 <= k <= n

Minimum Operations to Make Array Equal II solution leetcode

Minimum Operations to Make Array Equal II solution leetcode – You are given two integer arrays nums1 and nums2 of equal length n and an integer k.

Minimum Operations to Make Array Equal II solution leetcode

You can perform the following operation on nums1:

  • Choose two indexes i and j and increment nums1[i] by k and decrement nums1[j] by k. In other words, nums1[i] = nums1[i] + k and nums1[j] = nums1[j] - k.

nums1 is said to be equal to nums2 if for all indices i such that 0 <= i < n, nums1[i] == nums2[i].

Return the minimum number of operations required to make nums1 equal to nums2. If it is impossible to make them equal, return -1.

 

Minimum Operations to Make Array Equal II solution leetcode

Input: nums1 = [4,3,1,4], nums2 = [1,3,7,1], k = 3
Output: 2
Explanation: In 2 operations, we can transform nums1 to nums2.
1st operation: i = 2, j = 0. After applying the operation, nums1 = [1,3,4,4].
2nd operation: i = 2, j = 3. After applying the operation, nums1 = [1,3,7,1].
One can prove that it is impossible to make arrays equal in fewer operations.

Example 2:

Input: nums1 = [3,8,5,2], nums2 = [2,4,1,6], k = 1
Output: -1
Explanation: It can be proved that it is impossible to make the two arrays equal.

 

Minimum Operations to Make Array Equal II solution leetcode

  • n == nums1.length == nums2.length
  • 2 <= n <= 105
  • 0 <= nums1[i], nums2[j] <= 109
  • 0 <= k <= 105

Minimum Common Value solution leetcode

Minimum Common Value solution leetcode – Given two integer arrays nums1 and nums2, sorted in non-decreasing order, return the minimum integer common to both arrays. If there is no common integer amongst nums1 and nums2, return -1.

Minimum Common Value solution leetcode

Note that an integer is said to be common to nums1 and nums2 if both arrays have at least one occurrence of that integer.

 

Example 1:

Input: nums1 = [1,2,3], nums2 = [2,4]
Output: 2
Explanation: The smallest element common to both arrays is 2, so we return 2.

Minimum Common Value solution leetcode

Input: nums1 = [1,2,3,6], nums2 = [2,3,4,5]
Output: 2
Explanation: There are two common elements in the array 2 and 3 out of which 2 is the smallest, so 2 is returned.

 

Minimum Common Value solution leetcode

  • 1 <= nums1.length, nums2.length <= 105
  • 1 <= nums1[i], nums2[j] <= 109
  • Both nums1 and nums2 are sorted in non-decreasing order.

Jane Goodall is a famous scientist in what field?

In 1960, 26-year-old primatologist Jane Goodall began studying chimpanzees at the Gombe Stream National Park in Tanzania. Within the year, she made groundbreaking discoveries that chimpanzees were actually omnivores (not vegetarian as previously thought) and could use tools. This was only the beginning of a decades-long career that challenged humanity’s place in the world.

George Washington Carver proposed what crop as an alternative to cotton?

George Washington Carver proposed what crop as an alternative to cotton? – George Washington Carver proposed a number of alternative crops to cotton for farmers to grow, including sweet potatoes, soybeans, peanuts, and cowpeas. These crops would provide food for the farmer and his family, as well as income from the sale of the produce. Carver also encouraged farmers to rotate their crops, which would improve the soil, control pests, and reduce erosion. He also promoted the use of legumes to enrich the soil.

George Washington Carver proposed what crop as an alternative to cotton?

  1. Corn
  2. Peanuts
  3. Wheat
  4. Sugarcane
The correct answer is Peanuts.

George Washington Carver proposed what crop as an alternative to cotton?

George Washington Carver proposed the use of crop rotation to replenish the soil, the use of various plant-based products for industrial and commercial use, and the use of agricultural research to help farmers improve their economic situation. He also suggested the use of peanuts, sweet potatoes, and other crops as a source of food and income for farmers. He proposed a number of innovative uses for these crops, such as making soaps, dyes, and medicines, as well as for animal feed, oil, and molasses. He also campaigned for the use of soil conservation techniques, such as terracing, to reduce erosion.

Agricultural scientist George Washington Carver changed the future of farms across America through his studies of soil chemistry. Carver discovered that years of growing cotton had depleted the soil of crucial nutrients, resulting in low crop yields. He suggested planting nitrogen-producing plants, such as peanuts and other legumes, to restore the soil. This crop rotation technique proved a great success for farmers. The most well-known Black scientist of early 20th century, Carver set out to repurpose the new surplus of peanuts and invented a range of products using the legume, earning him the nickname “Peanut Man.”
