As per the rules followed in the above steps, find out in the given questions the appropriate step for the given input.

Input : "Over Go For through at one" Which step will be the last step of the above input?

Logic: Operations applied in each step are defined below:
Step I to step VII: Words are arranged in dictionary order from left to right. If there are two similar words in statement then the words with first letter in capital will be arranged first before the second one.
Input: Over Go For through at one

Step II: at For Over Go through one

Step III: at For Go Over through one
