Exercise 1:Write a python program to count the occurrences of one string in another string and display it to theuser in the desired format. Follow the given steps to get a valid mark:Prompt the user to enter two strings str1 and str2 as arguments.Define a recursive function named as countSubStr(str1, str2) where str1 and str2 are strings.The function should calculate the occurrences of the str2 in str1 and return it as an integer.Display the output in main function as given below.SAMPLE RUN 1:st

(Count occurrence of numbers) Write a program that reads at most 100 integers between 1 and 100 and counts the occurrence of each number. Assume the input ends with 0 . Here is a sample run of the program: Enter the integers between 1 and 100: 2 5 6 5 4 3 23 43 2 0 2 occurs 2 times 3 occurs 1 time 4 occurs 1 time 5 occurs 2 times 6 occurs 1 time 23 occurs 1 time 43 occurs 1 time | Numerade
