Suppose the following problem statement is given to you and you are planning to write a code for this problem. Problem statement: Let str be a string that contains any number of symbols from this set {a, b, c, .. z, 2, .. 9}. In other words, these strings are combinations of small case letters and digits from 2 to 9. Note that strings cannot have two consecutive digits or cannot end with a digit such as a23b4, and they cannot contain only digits such as 324, 999 etc. Samples of some valid str's are 2ab3d, b4t2cd, ca5f3g2at etc. Assume that the input str is always valid, so input validation is not necessary. Your program must create and print a new string (a copy of str) such that for each occurrence of a digit followed by a letter in str, the new string will have that letter repeated digit number of times, i.e., 2a will be replaced by aa, 3b will be replaced by bbb, etc. Other letters will remain same, Some sample strings and the expected outputs are as follows. Sample str = 2ab3d, expected output = aabddd Sample str= b4t2cd, expected output = bttttccd

Sample str = ca2f3g2at, expected output = caffgggaat Sample str = ca2f3g2at, expected output = caffgggaat Sample str = 3d2c4aefg, expected output = dddccaaaaefg Sample str = bdcagt, expected output = bdcagt Recall that there are four elements of the computational thinking process that we should apply to solve a given problem. Mention the name of each element and then briefly describe how you will apply that element to solve this problem. Note, you do not have to write a python code for this problem.
