I’ve checked this case as well and my answer is correct , my doubt is that I cant reduce my time how should I do it.
first i tried the question by brute force then test case 0 stucks!!–https://ide.codingblocks.com/s/181334
then i tried the question by sorting array and then calling the function for finding sum pairs then test case 1 stucks!!—https://ide.codingblocks.com/s/181372

@Yuvraj_Luhach
for your brute force you did not have to take the same element again so 3+3 woud not be answer for 6 as a sum .for that start you for loop for j from i+1 ,not i in line 14

#6

for when u are forming an array and sorting it to call sum ,You have not included when the array value might be any negative integer.
just add
else
lo++;

after your else if condition for when a[lo]+a[hi] <c
