English Description: Design an algorithm to find the kth number such, the only prime factors is 3, 5, and 7Idea: Factorization can only be 3,5,7, set this number to Val, then val = (3^i) (5^j) (7^n) (i,j,n>=0), obviously the 1th number is 1, 2nd is 1*3, 3rd is 1*5, 4th is 1*7, 5th is 3*3, 6th is a 5, the 7th one for 3*7 ...If the number of money k-1 into a linked list R, it can be seen that the number of K is 3 or 5 or 7 times the number of previous k-1 one, to get a minimum number of R has not

Now many telecom companies have launched access network products and their operation management system, but the access network of different manufacturers still difficult to achieve unified network management, this is precisely because they can only meet a level or a number of levels of consistency, rather than complete consistency. The formation of access network vend

established the general theory of relativity. The equator radius of mercury is about 2440 km, which is 38.3% of the earth's size. The mass is 5.6% × 3.33 grams, which is also 1026 of the earth's size. The average density is 5.6% grams/cm. 3, second only to the earth, the acceleration of surface gravity is 373 cm/second 2. The inversion rate is 0.06, and the color index is + 0.91, which is slightly smaller than that of the moon. The surface of mercury is very similar to the moon, with many diffe

What is a four-digit number of points.
The quartile, which is statistically, arranges all the values from small to large and divides them into four equal points, with a score of four in the three-point position.
The 14th Division (Q1), also known as the "smaller four", is equal to the number of all the values in the sample from small to large after the 25th.
The 24th (Q2), also known as the "median", is equal to the number of all values in
