function countChars(string, character) { var result = string; var count = 0; var i = 0; while ( i < string.length) { if (result[i] === character) { count = count + 1 ; } 我可以猜到这条路可能会奏效。斯蒂有什么理由让结果出现吗? function countChars(string, character) { ...

COUNT(ALL <expression>)evaluatesexpressionfor each row in a group, and returns the number of nonnull values. COUNT(DISTINCT *expression*)evaluatesexpressionfor each row in a group, and returns the number of unique, nonnull values. COUNTis a deterministic function when usedwithoutthe OVER and ORDER...
BOXCOUNT(C,'slope') also shows the semi-log plot of the local slope DF = - dlnN/dlnR as a function of R. If DF is contant in a certain range of R, then DF is the fractal dimension of the set C. The execution time depends on the sizes of C. It is fastest for powers ...
