/** *把1到100之间的数的偶数相加 */ class Demo{ public static void main(String[] args){ int i =1; int sum = 0; do{ if(i % 2 != 0){ sum += i; } //累加器需要在if语句外面 i++; }while(i <= 100); System.out.println(sum); } }
#-*- coding:UTF-8 -*- #环境:python3 print("Enter the numbers between 1 and 100:") enterList=[] #记录输入的元素 while 1: a = int(input(">>>")) #将输入转换为int型 if a == 0: print ("Your input:",enterList) break #结束输入 if a<1 or a&g
declare i number:=1; j number:=0; sum1 number:=0;begin while(i<100) loop i:=i+1; j:=2; while(mod(i,j)!=0) loop j:=j+1; if(i=j) then exit; end if; end loop; if(i=j) then sum1:=sum1+i; DBMS_OUTPUT.PUT_LINE(i); end if; end loop; DBMS_OUTPUT.PUT_LINE(SUM
代码如下: import random n = 0 sum = 0 while n < 10: num = random.randint(1, 100) sum = sum + num n += 1 print(num, end=",") print() print("10个数的和为:%d" % sum) print("10个数的平均值为:%.2f" % (sum / 10)) 运行结果:
不管是while循环还是for循环,原理都是取根号,循环到取根号后的数,至于为什么需要循环到开根后的数,我想主要是因为一个数的分解因子在开根号后的数向上取整以下吧. 话不多说,上代码: while循环: while循环原理如下: i = 2 while i <= 100: # 内层循环 j 从2循环到根号 i j = 2 while j <= (i / j): # j <= (i/j) 等效于 j*j <= i 也就等于 j <= 根号 i if i % j == 0: br
依然是while循环四步骤 初始化变量 条件判断 条件执行体 最后就是输出答案就可以了 点击查看笔者代码 a = 1 sum = 0 while a <= 100: if (a+1)%2:#if not a%2也是可以的,注意与或非的使用and or not sum+=a a+=1 print(sum) 较为简单的一个程序,但是需要注意对a变量的改变,否则会成为一个死循环,注意这边的sum变量需要先进行声明,否则python编译器对于sum+=a就会报错,因为找不到sum对象
Given two binary trees, write a function to check if they are the same or not. Two binary trees are considered the same if they are structurally identical and the nodes have the same value. Example 1: Input: 1 1 / \ / \ 2 3 2 3 [1,2,3], [1,2,3] Outpu
