Line no: 10 will overright index value sine there are duplicate values in the input.. May be we might need to keep tract of all indexes in a hash as a seperate list collection?

Ipdi panalamae brother Like sliding window concept instead of using maps Example -4, -1, -1, 0, 1, 2 idhula Frst window size 2 vachu adha slide panite pogalam [-4, -1], -1, 0, 1, 2 ipo andha frst two add panna -5 varum ippa adutha loop la remaining number la enga +5 iruku pakalam Then next iteration -4, [-1, -1], 0, 1, 2 -1-1=-2 Now we need to find 2 in remaining numbers like 0, 1, 2 We'll find it and we can add it ro our set Then next iteration -4, -1, [-1, 0], 1, 2 -1+0 = -1 Now we need +1 which is next to 0 Now we can add -1, 0,1 in our set After that -4, -1, -1, [0, 1], 2 we need 1 but there is only 2 remains Then -4, -1, -1, 0, [1, 2 ] now there is no numbers left to add as 3rd integer And our loop ends Idhu crct ah varum la brother?
