to find the max you need to look at each element from the one after the i-th element to the end of the arrayhow to find max element from remaining array?
each zero value in the array is replaced by the largest odd value to the right
public int[] zeroMax(int[] nums) {
for (int i = 0; i < nums.length; i++) {
if (nums[i] == 0) {
if (nums[i] == 0) {
int largest=nums[i];
for (int j = i; j < nums.length; j++) {
if(nums[j]>largest){
largest=nums[j];
}
if(largest>0){
nums[i]=largest;
}
}
}
}
}
return nums;
}
Expected Runi passed all tests with one 0. How pass tests with more than one 0?

something like above?But you need to establish the value for largest odd first.i thought i did as below?
