PhonePe Placement Papers 2025 - Actual Questions & Solutions

DSA Coding Problems (2025)

Question 1: Merge Intervals

Q1: Given an array of intervals, merge all overlapping intervals.

Solution (Java):

public int[][] merge(int[][] intervals) {
    if (intervals.length <= 1) return intervals;

    Arrays.sort(intervals, (a, b) -> Integer.compare(a[0], b[0]));
    List<int[]> merged = new ArrayList<>();
    merged.add(intervals[0]);

    for (int i = 1; i < intervals.length; i++) {
        int[] current = intervals[i];
        int[] last = merged.get(merged.size() - 1);

        if (current[0] <= last[1]) {
            last[1] = Math.max(last[1], current[1]);
        } else {
            merged.add(current);
        }
    }

    return merged.toArray(new int[merged.size()][]);
}
