并且在这个循环过程中记录位数。在下一步还原时,依据当前位数算出要乘以多少个0,从queue中取出来的数就是从个位开始的数,相当于reverse了。 因为取得数字的过程中依据取余,所以符号可以得以保留,并且对于10,100也能保证reverse的正确性。 对于溢出并没有做特殊处理。 代码如下: 1publicintreverse(intx) { 2Queue...

Leetcode7 Reverse Integer Java实现及分析 首先 public int reverse(intx) { int ans = 0; while(x!=0) { int temp = x%10; x/=10; ans = ans*10+temp; } returnans; } 但是这样无法检验最终结果是否溢出。 我们可以看到,溢出的原因是ans*10+temp>MAX或ans*10+temp<MIN。一旦溢出,ans就变为了...
