Given an array of words representing your dictionary, you test words to see if it can be made into another word in dictionary. T
his will be done by removing characters one at a time. Each word represents its own first element of its string chain, so start with a string chain length of 1. Each time you remove a character, increment your string chain by 1. In order to remove a character the resulting word must be in your original dictionary. Your goal is to determine the longest string chain available for a given dictionary. for example, given a dictionary [a, and, ab, bear] the word and could be reduced to an and the word an to a. The single character a can not be reduced to any further as the null string is not in the dictionary. This would be the longest string chain, having a length 3. The word bear can not be reduced at all.

Answer:
33.56 ft^3/sec.in
Explanation:
Duration = 6 hours
drainage area = 185 mi^2
constant baseflow = 550 cfs
<u>Derive the unit hydrograph using the inverse procedure </u>
first step : calculate for the volume of direct runoff hydrograph using the details in table 2 attached below
Vdrh = sum of drh * duration
= 29700 * 6 hours ( 216000 secs )
= 641,520,000 ft^3.
next step : Calculate the volume of runoff in equivalent depth
Vdrh / Area = 641,520,000 / 185 mi^2
= 1.49 in
Finally derive the unit hydrograph
Unit of hydrograph = drh / volume of runoff in equivalent depth
= 50 ft^3 / 1.49 in = 33.56 ft^3/sec.in
