"Problem description" the split of natural number: any one of the natural number greater than 1 N,Can always be divided into several natural numbers of the sum, and there are many methods of splitting. Try to find all the split of N.For example, natural number 5, you can have some of the following splitting methods:5=1

Introduction In 1982, tateaki. Sasaki and yasumasa Kanada published a paper: practically Fast Multiple-Precision Evaluation of log (X ). In this four-page paper, they introduced a quick way to calculate the natural logarithm.Algorithm. C # Program We know that the system. Math. Log method in the. NET Framework class library can only calculate the natural logarithm of the dobule data type. Now we impleme

Label: style blog color sp for div on problem logRepresent a positive integer as the sum of consecutive natural numbers. For example, if an integer 15 is given, the continuous natural numbers to be output are 1 + 2 + 3 + 4 + 5 = 4 + 5 + 6 = 7 + 8 = 15. The continuous natural number sequence in the question can be regarded as an ascending ordered array, and the fi

Some numbers in a positive integer can be obtained by the addition of consecutive natural numbers, such 1 + 2 = 3 4 + 5 = 9 2 + 3 + 4 = 9 Three of its problems are listed here: 1. Write a program. For any 64-bit positive integer, output the formula of all its possible continuous natural numbers? 2. What kind of number cannot be obtained by adding continuous natural
