Question
What is the smallest number in the penultimate step of
the given input? Study the following information carefully and answer the given questions. A word and number arrangement machine when given an input of words and numbers rearranges them following a particular rule. The following is an illustration of input and rearrangement. Input: 95738   68537  87843  38594   58234  73544 Step I: 35  95738    68537     87843  58234  73544 Step II: 523  35    95738    68537   87843    73544 Step III: 537  523    35        95738    87843   73544 Step IV: 735  537    523        35        95738    87843 Step V: 73    735   537    523        35        95738   Step VI: 573   73    735   537    523        35     Step VI is the last step of the above input. As per the rules followed in the above steps find the appropriate step for the given input. Input: 74936    58967   49772    83529    36947   66723Solution
All the numbers given in input are arranged in each step (in ascending order from left) after removing non-prime digits from it. One number is arranged in each step and every new number is placed at the left end after shifting previous numbers one place towards right.
