Step 1: Input Reading

I started by reading the integer value n, which represents the number of elements in the array.
I then read the n integer values into an array.

Step 2: Processing Non-Zero Elements

I initialized a variable count to keep track of the position where the next non-zero element should be placed.
I iterated through the array and for each non-zero element found, I placed it at the index indicated by count and incremented count.

Step 3: Placing Zeros

After placing all non-zero elements at the beginning of the array, I filled the remaining positions with zeros. This was done by iterating from the index count to the end of the array.

Step 4: Output the Result

Finally, I printed the array with non-zero elements followed by zeros.

Step 1: Input Reading

I started by reading the integer value n, which represents the number of elements in the array.
I then read the n integer values into an array arr.

Step 2: Counting Occurrences

I initialized three counters: countZero, countOne, and countTwo to keep track of the number of 0s, 1s, and 2s in the array.
I iterated through the array, incrementing the respective counter based on the value of each element (0, 1, or 2).

Step 3: Constructing Sorted Array

Using the counts obtained in the previous step, I reconstructed the array by first placing all 0s, then all 1s, and finally all 2s.
I used a variable j to keep track of the current index where the next value should be placed.

Step 4: Output the Result

I printed the sorted array, where the elements are ordered from 0 to 2 based on their risk severity.
