If the controlling expression needs to be evaluated after the loop body, the do-while loop may be used. If the execution of the loop needs to be terminated at some point, break statement can be used as a terminating statement. If the execution of the loop needs to be continued at ...

本质上来看,快速排序应该算是在冒泡排序基础上的递归分治法。 void quicksoft(int * arr, intL, intR){intleft=L,right=R;int pivot = arr[left];while(left<right){while(left<right&& arr[right] >= pivot){right--;}if(left<right){arr[left] = arr[rig...

while:while loop for:for loop 输出引脚Index可以显示当前是第几个循环 for each loop: Element 输出当前数组元素的值 do once:做一次,输入引脚自带重置和第一次是否开启 do N:循环几次 Flip Flop:交替执行 Gate和MultiGate:门——参考电路,Open时,enter输入才有Exit输出;Close时,无输出;Toggle交换。
