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:

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
