// Add the number to array
For (INT I = 0; I

// New a random number
Random random = new random ();
// Create the subscript of a random number
Int index;

We know that a function f can obtain a random number ranging from 1 to 5 with equal probability. How can we obtain a random number ranging from 1 to 7 with equal probability?
Int rand7 (){Int;While (A = rand5 () * 5 + rand5 ()> 26 );Return (A-3)/3;}
AlgorithmThe idea is:1. Use rand5 () * 5 + rand5 () to generate 6
Question:
It is known that a function rand7 () can generate a random number ranging from 1 to 7. Please provide a function that can generate a random number ranging from 1 to 10.
Ideas:
If we know that a function can generate a random number ranging from 1 to 49, how can we generate a random number ranging from

Problem description: there are now n ordered arrays in M groups, such as {1, 2, 3, 4}, {2, 3, 6}, {1, 3, 5, 7 }, select the data smaller than K in these arrays and return this value.
Idea: Compare the minimum data selected each time by referring to the process of merging two Arrays
1. Define the selection position arra
