Write a method to generate a random number between 1 and 7, given a method that generates a random number between 1 and 5. The distribution between each of the numbers must be uniform.
You are given n real numbers in an array. A number in the array is called a decimal dominant if it occurs more than n/10 times in the array. Give an O(n) time algorithm to determine if the given array has a decimal dominant.
Implement a function getbits, that returns the(right adjusted) n bits that begin at position p of an integer. Assume bit position 0 is at the right end and that n and p are sensible positive values.
input :- rand_5
ReplyDeleteoutput :- rand_7
soln:-
((rand_5()-1)*3/2)+1 gives number in the range 1 to 7
rand_5() gives 1 to 5
rand_5()-1 gives 0 to 4
and so on ...
