鸡兔同笼代码

//有雉兔同笼，上有三十五头，下有九十四足，问雉兔各几何？

    int rabbit = 0;    //兔子数量

    int hen = 0;    //鸡数量

    for (int i = 1 ; i < 35 ; i++ ) {

        for (int j = 1 ; j < 35 ; j++ ) {

            rabbit = i;

            hen = j;

            if (rabbit + hen == 35 && rabbit * 4 + hen * 2 == 94) {

                NSLog(@"rabbit = %d , hen = %d",rabbit,hen);           
//rabbit = 12 , hen = 23

            }

        }
