我最近阅读了关于线段树中的惰性传播并对其进行了编码。但是当假设我需要除以值而不是添加值（= val）时我被卡住了。怎么做？请帮忙
我的更新功能如下：
void update_tree(int node, int a, int b, int i, int j, int value) {
if(lazy[node] != 0) { // This node needs to be updated
tree[node] += lazy[node]; // Update it
if(a != b) {
lazy[node*2] += lazy[node]; // Mark child as lazy
lazy[node*2+1] += lazy[node]; // Mark child as lazy
}
lazy[node] = 0; // Reset it
}
if(a > b || a > j || b < i) // Current segment is not within range [i, j]
return;
if(a >= i && b <= j) { // Segment is fully within range
tree[node] += value;
if(a != b) { // Not leaf node
lazy[node*2] += value;
lazy[node*2+1] += value;
}
return;
}
update_tree(node*2, a, (a+b)/2, i, j, value); // Updating left child
update_tree(1+node*2, 1+(a+b)/2, b, i, j, value); // Updating right child
tree[node] = max(tree[node*2], tree[node*2+1]); // Updating root with max value
}
