Write a Python program to use set operations to find the missing number in an array representing a continuous range. Write a Python program to iterate over a range from 10 to 20 and return the number that is not present in the array. Write a Python program to implement a function that t...
Since the array contains all distinct elements and all elements lie in range 1 ton+1, use this property to solve this problem. Initially check if the missing number lies in range 1 ton. If a missing number is not found in range 1 ton, then the missing number isn+1. To check if a ...

The np.isnan() function in NumPy is used to identify NaN (Not a Number) values in an array.This function checks each element in the array and returns a boolean array of the same shape, where each element is True if the corresponding element in the original array is NaN and False ...
