1.) Write a python program for given example :
example: a4b3c2
output: aaaabbbcc
2.) Python program to interchange first and last elements in a list
Input : [12, 35, 9, 56, 24]
Output : [24, 35, 9, 56, 12]
3.) Python program to find second largest number in a list
Input : [12, 10,35, 9, 56, 24,56,55]
Output : 55
4.) Check if two lists have at-least one element common or not
Input : a = [1, 2, 3, 4, 5]
b = [5, 6, 7, 8, 9]
Output : True
Input : a=[1, 2, 3, 4, 5]
b=[6, 7, 8, 9]
Output : False
