Cortex-A OR Cortex-MQuestion DescriptionA smartwatch is a very useful device developed by several companies these days including Apple, Samsung, Motorola and several others. It has a touch screen interface providing features like GPS tracking, heart rate and sleep monitoring etc. with power efficient batteries. The ARM Cortex processors are used in smartwatches providing several benefits.

Suppose we have to choose between ARM Cortex-A or Cortex-M series architecture for our next generation smartwatch. Which one would you select between the two and why? Support your selection of either architecture with solid reasoning considering memory management, cost, performance and chip size.Cortex-A OR Cortex-MQuestion DescriptionA smartwatch is a very useful device developed by several companies these days including Apple, Samsung, Motorola and several others.

Q1. Write a program to input a string and count the occurrence of the word ‘the’(in any case) in the string.

For eg: if the input is:  The sun rises in the east.

Output should be:2

Q2. Write a program to input a string and count the number of words in it.                                               

For eg: if the input is: I like computer science.

Output should be:4

Q3. Write a program to input a string and print at which position a particular word exist.                          

For example :if the string is: I like computer science.

Word is:like(to be taken from user)

Output is 2 (as like is the second word in the string.)

Write a program that takes as input two numbers n (integer) and x (double), and prints arctan(x) evaluated by taking n terms of the Taylor series (using x0 =0):

arctan(x) = x - x ³ /3 + x ⁵ /5 - x ⁷ /7 …

Q1. Write a program to input n elements of a list and display  the following pattern:                         

Eg. If the elements entered by the user is :  1  2   3   4   5

The pattern printed should be:

1 0 0 0 0

1 2 0 0 0

1 2 3 0 0

1 2 3 4 0

1 2 3 4 5

Q2. Write a program to input a list of n elements and print all the prime numbers(if any) in the list. If the list does not contain any prime number,display ”No Prime Number in the List"

Q3. Write a program to input a list of N elements and rearrange it so that all odd elements appears after all even elements of the list.

Eg. If the entered list is:  1  2  3  4  5  6

Then the output list should be:

2  4  6  1  3
