In rahul's school every student is uniquely identified by a string which is printed on the id card of the student .This unique id is comprised of letters and digits separated by hyphens into groups of different lengths.The college administration decides to standardize this unique id on the id card by regrouping the letters of the previous unique id to a fixed group length.the college administration also does not want to have lowercase letters in the new id.you need to help the college administration with this task.Given the previous id,and the no.of characters to group,you need to generate the new id
note:while generating the new unique id ,group the characters from right to left
input:the 1st line containing a string S representing a unique id.
the 2nd line containing an integer N representing group length

A psychologist has measured the IQ for a group of 30 children, now in the third grade, who had been regularly exposed to a new interactive, computerized teaching device. The mean IQ for these children is X = 106.
a. Test the null hypothesis that these children are no different from the general population of third-graders (μ = 100, σ = 6) using alpha = .05.
Mixing sodium bicarbonate and citric acid in a solution produce carbon dioxide that shows as fizz. Given the balanced reaction below, what is the amount in grams of citric acid should be added to 0.5 g sodium bicarbonate to have a complete reaction?
3 NaHCO3 (aq) + C6H8O7 (aq) ---> 3CO2 (g) + 3H2O (l) + Na3C6H5O7 (aq)
G: 0.5 g NaHCO3
F: g of C6H8O7
MM: 1 mol NaHCO3 = 84.01 g NaHCO3
1 mol C6H8O7 = 192.12 g C6H8O7
MR: 1 mol C6H8O7 = 3 mol NaHCO3
