The function allSubstring(str, 3) finds all the occurrences of one string in another and returns a list of positions where the second string s occurs in the first string str, even if there are overlaps. For example, allSubstring("abab", "ab") will return [0, 2] and allSubstring("aaa", "a") will return [0, 1, 2]. The function needs to be completed as several lines have been omitted. Identify the number of the lines that are needed to complete the omitted lines in the code (vertical bars indicate where the line of code is indented). Complete the code by choosing the appropriate lines of code from the list of available lines (click on the attachment below for the list of available lines and the code to complete). List of Lines to Choose From: 1) found = True 2) found = False 3) if i == j: 4) if str[i== s(): 5) if str[i+1] == s[i]: 6) if str[i+j] == s[j] Code Segment to Complete: def allSubstrings(str,s): plst = 0 for i in range(0, len(str) - len(s) + 1): j = 0 found = True while i
