dont give the same solution again .10 min left fast Array Indexing: Knowing the basics of array indexing is important for analysing and manipulating the array object. NumPy offers many ways to do array indexing. O slicing: Just like lists in python, NumPy arrays can be sliced. As arrays can be multidimensional, you need to specify a slice for each dimension of the array. O Integer array indexing: In this method, lists are passed for indexing for each dimension. One to one mapping of corresponding elements is done to construct a new arbitrary array. O Boolean array indexing: This method is used when we want to pick elements from array which satisfy some condition
in C programing Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6, 7, 7, 12, then isSorted(a, 5) should return 1 . If array b stores 3, 4, 9, 8, then isSorted(b,4) should return 0.int isSorted(int *array, int n){
Assignment Write a program that reads a 2D array of chars, checks, and corrects each char within this array, and print out the corrected 2D array. First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. • If the row index is an even number, a char can only be a lowercase English value. • If the row index is an odd number, a char can only be ?, 7', or X'. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen. NOTE: Checking the correctness of a char and correcting it (if necessary) MUST be done in the function with a…
