1.scan the array and find the maximum digits of integer. lets say m..
2.Again scan the array and pad the intergers whose digits are less that m (<
m) with zero's .. copy the new integers in a new array
3.sort the new array in desc order and carry the same even for original
array.
4. Now the original array contains the required output.
ex: original aarray 23,8,19,9,1
max digits : 2 (for 23 as well as 19)
step 2: new array 23,80,19,90,10
step3. sort .. 90,80,23,19,10 .. and corresponding original is .. 98231910.
original array contains the original output..
