NumPy, a popular library in Python, offers powerful tools for sorting arrays efficiently. Thesortfunction in NumPy can be applied to one-dimensional arrays and allows sorting in both ascending and descending order. To sort a NumPy array, you can simply use the following syntax: import numpy as...
To find indices of matches of one array in another array, we usenumpy.in1d()withnumpy.nonzero(). Thenumpy.in1d()is used to test whether each element of a 1-D array is also present in a second array. It returns a boolean array the same length asar1that isTruewhere an element ofar...

1. Using Python, write a function named longEnough that takes two parameters: a) s, a string b) threshold, a non-negative integer The function longEnough should return True if the length of s is at le 1. We are running the Insertion Sort algorithm on the array A = 3, 9, 4, 7,...
