Can you solve this real interview question? Ways to Split Array Into Good Subarrays - You are given a binary array nums. A subarray of an array is good if it contains exactly one element with the value 1. Return an integer denoting the number of ways t
Here a split of an array (with integer elements) is good if the array is split into three non-empty contiguous subarrays respectively from left to right, and the sum of the elements in left side is less than or equal to the sum of the elements in mid part, and the sum of the ...
Since we need to compute subarray sum, so we should get the prefix sum array ps. Notice that nums[i] is nonnegative, so ps is non-decreasing. Using ps we can either do a linear scan with binary search, or just a linear scan. Solution 1. O(N*logN), fix the start index of the...
[array([[1, 2]]), array([[3, 4]]), array([[5, 6]])] Example 2: Split an Array by Index import numpy as np array1 = np.array( [1, 2, 3, 4, 5, 6] ) # indices at which array is split splitIndices = [2, 5, 8] # split into subarrays splitArrays = np.split(arr...

# Quick examples of numpy array split # Example 1: Use numpy.split() function arr = np.array([5,7,9,11,13,19,23,27]) subarrays = np.split(arr,4) # Example 2: Using numpy.split() function # To split the array into subarrays arr = np.array([5,7,9,11,13,19,23,27]) ...
numpy.array_split(ary, indices_or_sections, axis=0) Parameters: Return value: Example: Splitting a NumPy array into equal-sized subarrays using numpy.array_split() >>> import numpy as np >>> a = np.arange(9.0) >>> np.array_split(a, 4) ...
In the above code, the numpy.split() function is used to split an input array 'a' at specified positions given as a list argument [4, 5, 6, 7]. This will split the array 'a' into subarrays at the positions 4, 5, 6, and 7. ...
